Determine which of the following statements is true about energy in ecosystems.
A. Primary producers lose 20% of the energy they absorb as urine and feces.
B. Consumers pass on 20% of the energy they get from a lower trophic level.
C. Primary consumers lose 60% of the energy they absorb from producers as urine and feces.
D. 10% of the energy Primary consumers absorb is lost as heat.
The community along with the biotic and abiotic factors makes the ecosystem. In the ecosystem, 10% of the energy primary consumers absorb is lost as heat. Thus, option D is correct.
What is an ecological pyramid?An ecological pyramid is the graphical presentation of the organism and the flow of energy at each trophic level. The trophic level constitutes the producers and the consumer.
The flow of energy follows the 10% energy rule where each trophic level loses and gains only a certain amount of heat. The heat is lost as excretory products in the environment.
The maximum amount of energy is gained by producers which passes to the primary consumers (10%), secondary consumers (1%), and the upper trophic level.
Therefore, option D. primary consumers absorb only 10% of energy.

What would you expect to happen to your Expiratory Reserve Volume when you are treading water in a lake
The Expiratory Reserve Volume will decrease when an individual is treading water in a lake.
What is Expiratory Reserve Volume?Expiratory Reserve Volume, ERV, is the additional volume of air which can be forcefully expired with maximum extra effort beyond the volume that can be expired in normal expiration.
ERV normally decreases with exercise.
Therefore, the Expiratory Reserve Volume will decrease when an individual is treading water in a lake.

Energy in this ecosystem passes directly from the sun to.
Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement.

4. Which of the following is a parasite?
(a) Mushroom
(b) Fungi
(c) stem
(c) Cuscuta
(d) haustoria
(d) Rhizobium
Answer:
C: Cuscuta is a parasite .
Explanation:
Mushrooms are a part of the fungi domain meaning that it is a decomposer. I'm not too sure whether it means stem body cells or a stem in a plant. Either way both are not parasites. Cuscuta is a plant that does not have chlorophyll (they can't carry out photosynthesis) and since this plant cannot make its own food, it feeds off a host plant that can make food. An organism that needs a host to survive is called a parasite. Haustoria is a part of some parasites however it itself is not one. And finally Rhizobium is a bacteria that converts Nitrogen into ammonia which helps plants.

The first three strata of the epidermis consists of ______ keratinocytes and the most superficial strata contain ______ keratinocytes.
The first three strata of the epidermis consists of living keratinocytes and the most superficial strata contain dead keratinocytes.
What is the role of the keratinocytes?Keratinocytes are the most common cell type in the epidermis, the outermost layer of the skin, accounting for over 90% of all cells. They begin in the epidermis's deepest layer, the stratum basale, and progress to the skin's last barrier layer, the stratum corneum.
The stratum basale (germinatum) is the innermost (deepest) layer of the epidermis, followed by the stratum spinosum, stratum granulosum, stratum lucidum (when present), and the stratum corneum, which is the outermost layer.

Jayden is researching the Earth's
plates. How would he describe the
relationship between the Earth's plates
and soil and rocks?
Answer:
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
The Earth's plates have a crucial relationship with soil and rocks. This connection is characterized by the plates' movement influencing the formation, distribution, and composition of soil and rocks across the planet.
The asthenosphere, which is semi-fluid beneath them, is separated into many tectonic plates that make up the Earth's lithosphere. Convective currents in the mantle cause these plates to move constantly. Processes like subduction, in which one plate falls beneath another, and rifting, in which plates move apart, are fueled by this movement. Mountains, valleys, and oceanic basins are all the result of these dynamic processes, which have a significant impact on the surface of the Earth.
Through volcanic activity and metamorphism, interactions between the plates also aid in the production of different types of rocks. Therefore, the distribution and makeup of soils and rocks on our globe are significantly shaped by plate movement, which also has an impact on landscapes, ecosystems, and geological characteristics.
