Lab: Interdependence of Organisms

Interdependence Of Organisms

Question Being Answered:

How can the presence of one species benefit another in the same ecosystem?

Hypothesis:

If plants grow in soil that contains worms the plants growth will be greater because worms are able to help decompose organic matter and help distribute it through the soil in a form plants are able to use.

Process Of Lab:

In this lab you will grow two different groups of plants. Group A is considered the experimental group which will grow in soil with worms, Group B is considered the control group which will grow in soil without worms. After the plants grow you have to measure the plant growth for both groups and compare them.

Independent & Dependent

Independent Variable: Presence Of Worms

Dependent Variable: Plant Growth

Safety Procedure

Be sure to follow the safety procedure which means to

Wear safety goggles and lab gown while doing the experiment

Keep lab behavior purposeful

Look over the soil contents and make sure to follow warnings provided on any equipment

Wash hands and lab equipment once done with experiment

Treat living organisms with respect and provide proper care

Report any accidents that happen in the lab to your teacher

Lab Procedure

Step 1: Gather Materials

Two trays that are 10 cm 4’ deep

Potting soil

Lima bean seeds which need to be soaked overnight

Location with sunlight or growth lights

Worms

Graduated cylinder

Water

Black marker

Ruler with metric markings

Step 2: Prepare Two Trays Of Lima Bean Plants

Label the trays Control Group and Experimental Group

Add approximately 6-7 cm of soil to each tray

Plant 6 lima bean seeds in each tray being 2 cm deep and label the plants 1-6

Step 3: Give The Plants Water And Light During Sprouting Time

Keep the environments for both groups identical

Water all the plants following the watering schedule that was recommended on the seed packaging

Use the graduated cylinder to ensure the same amount of water is being given to both groups

Make sure all plants get the same amount of light

Step 4: Measure The Heights Of The Plants At The End Of Week 1

Measure the height of all twelve plants to the nearest cm. If a plant dies mark an x on the data table for that plant and write it in your notes

Use a calculator to find the average heights of the living plants in each groups

Calculate the difference in those average heights by subtracting the average height of the plants in the control group. Use this difference as a basis for comparison

Record measurement observations in your notes and the health of the plants such as leaf colors and size, wilting, unusual growth, brown spots, and any other marks you see

Step 5: Add Six Worms To The Soil Of The Experimental Group Of Plants

Write descriptive notes about the condition of the worms in your notes

Step 6: Measure The Heights Of The Plants At The End Of The Week 3

Repeat step 4

Step 7: Measure The Heights Of The Plants At The End Of Week 5

Repeat step 4

Step 8: Check The Health Of The Worms At The End Of The Study

Are the worms still alive?

Do they all seem healthy?

Have they changed in any way? If so list the ways changed

Are there any new worms

Be sure to write descriptive notes about their conditions in your notes

Step 9: Dispose Of All Material According To The Directions From Your Teacher

Why is it more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain?

Answers

the trophic pyramid is the reason

what the trophic pyramid is:  Trophic pyramid, also called an energy pyramid, showing the progression of food energy. The pyramid base contains producers, organisms that make their own food from inorganic substances. All other organisms in the pyramid are consumers

- predators get little energy from the prey they eat so they must consume multiple prey

It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.

The trophic levels of food chain

The food chain is defined as a feeding pathway that consists of similar organisms that are placed in the same trophic levels.

Trophic levels in a food chain are those levels that is occupied by a group of organisms that have a similar feeding mode.

The plants which are the producers are at the lower trophic level while the carnivores are at the higher trophic levels.

The carnivores eats meat from other animals but not plant or plant products which obtain direct energy from sunlight.

Therefore, It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.

Explain the advantages to a plant of having its cell membranes surrounded by cell walls

Answers

Answer:

Advantage of cell walls

It protect and support the cell .

To give difinite shape for the cell.

Having cell walls surrounding cell membranes provides several advantages to plants, including structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture.

The cell wall is a rigid structure located outside the cell membrane in plant cells. It is composed primarily of cellulose, a complex carbohydrate. Here are the advantages of having cell walls:

Structural Support: Cell walls provide mechanical support to plant cells and help maintain the overall shape and structure of the plant. They allow plants to stand upright and withstand environmental forces such as wind or gravity. The cell walls of adjacent plant cells are interconnected, forming a strong network that provides stability to the plant as a whole.

Pathogen Protection: The cell wall acts as a physical barrier against pathogens such as bacteria and fungi. It prevents the entry of pathogens into the plant cells, reducing the risk of infection. Additionally, the cell wall can contain antimicrobial compounds and other defense molecules that provide further protection against pathogens.

Water Regulation: The cell wall plays a crucial role in regulating water balance within plant cells. It helps maintain turgor pressure, which is essential for cell expansion and overall plant growth. The cell wall allows water to enter and exit the cell in a controlled manner, preventing excessive water uptake or loss.

Cell Rupture Prevention: The rigid cell wall helps prevent cell rupture or bursting when the internal pressure within the cell increases. It provides strength and stability to the cell, allowing it to withstand internal pressure changes without bursting.

Overall, the presence of cell walls in plant cells offers significant advantages in terms of structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture. These advantages contribute to the overall health, growth, and survival of plants in diverse environmental conditions.

unfavorable for the growth and survival of the organism.

Answers

Answer:

Protozoa formed cysts and bacteria produces endospores.

Explanation:

Protozoa can survive in dry and unfavourable environments, by producing resting cysts that enable them to remain dormant until conditions are favourable while on the other hand, bacteria produce special dehydrated cells called Endospore which helps the bacteria to survive unfavourable environmental conditions.

what describes skeletal muscles​

Answers

"Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels."

Answers

Answer:

isolation is a significant factor in adaptation and speciation

Explanation:

In the theory of evolution by natural selection proposed by Darwin, adaptation refers to the adjustment of organisms to their environments in order to increase their chances of survival in that environment. In the Galapagos Islands, Darwin observed that finches had different types of beaks adapted to the type of food they ate. From this observation, Darwin proposed that finches evolved to eat different food sources. In this case, the islands lead to an adjustment (evolutionary) process by which geographically isolated individuals accumulate genetic differences in order to adapt them to the environmental conditions in the islands, which then may also prevent breeding between individuals from different islands when they are reunited (i.e., it may also lead to speciation).
