Answer:
1. The field of biology concerned with the relationships between species and their physical environments.
2. Abiotic components are non-living chemical and physical factors in the environment that influence ecosystems in ecology and biology. The term "biotic" refers to a living part of an ecosystem, such as plants and animals.
3. Since photosynthesis is the primary source of oxygen in the atmosphere, it is vital to living organisms. Photosynthesis is the process by which green plants and trees produce food from sunlight, carbon dioxide, and water in the atmosphere: it is their primary source of energy.
4. Decomposers break down dead plants and animals and return nutrients to the soil. Carnivores get their nutrition by eating other species. Herbivores obtain their energy from the plants they consume. Plant and animal forms of nutrition are used by omnivores.
5. Energy is required for all living organisms to develop and reproduce, sustain their structures, and react to their surroundings. Metabolism is a series of life-sustaining chemical processes that enable organisms to convert chemical energy stored in molecules into energy for cellular processes.
6. Organisms compete for resources such as air, water, food, and space in order to live. In areas where these are sufficient, organisms coexist peacefully, and in areas where resources are plentiful, the ecosystem boasts a diverse range of species (diversity).
7. The word "niche" is used in ecology to describe the role that an organism plays in a group. The physical and environmental conditions that a species needs (such as temperature or terrain) as well as the relationships it has with other species make up a species' niche (like predation or competition).
8. Prey animals are species that serve as food for predatory animals. Many predators could end up as food for larger predators. The top predator is a predator species that does not prey on other animals.

What kingdom (Plantae, Fungi, Animalia, or Protista) does each organism belong to? (no links)
Answer:
Plantae: herbs, plants, trees, bushes, grass....
Fungi: yeasts, molds, mushrooms
Animalia: all animals (not prokaryotes nor protists)
Protista: amoebae, red algae, dinoflagellates, diatoms, euglena, and slime molds
Answer:
Plantae: Kingdom Plantae
Fungi: Kingdom Eukarya
Animalia: Kingdom Metazoa or Animaliaanimals
Protista: Kingdom Protista
Explanation:
Kingdom Plantae includes familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae.
The Kingdom Fungi belongs to the domain Eukarya and it includes at least 11 separate groups
All animals are members of the Kingdom Animalia, This Kingdom does not contain prokaryotes or protists
Protists are eukaryotic organisms put simply, protists are all the eukaryotes that are not animals, plants, or fungi.

What is the kinetic energy of a 4,000 kg elephant that is running at 2 m/s? What is the kinetic energy of the elephant if it running at 4 m/s? How do the two kinetic energies compare with one another?
By definition of kinetic energy,
the kinetic energy of a 4,000 kg elephant that is running at 2 m/s is 8000 Jthe kinetic energy of a 4,000 kg elephant that is running at 4 m/s is 32000 Jthe kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.
Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.
Kinetic energy is represented by the following expression:
Ec = ½ mv²
Where Ec is kinetic energy, which is measured in Joules (J), m is mass measured in kilograms (kg), and v is velocity measured in meters over seconds (m/s).
In this case, you know:
m= 4000 kgv1= 2 m/sv2= 4 m/sThen:
Ec1 = ½ mv1²
Ec1= ½ 4000 kg× (2 m/s)²
Ec1= 8000 J
and
Ec2 = ½ mv2²
Ec2= ½ 4000 kg× (4 m/s)²
Ec2= 32000 J
You can see that the kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.
In summary:
the kinetic energy of a 4,000 kg elephant that is running at 2 m/s is 8000 Jthe kinetic energy of a 4,000 kg elephant that is running at 4 m/s is 32000 Jthe kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.Learn more about kinetic energy and mechanical energy:

The more diverse an ecosystem is —
A. the more threatened its populations are
B. the more similar the species will be
C. the more sustainable it is
D. the fewer varieties of species are present
The correct answer is C: the more sustainable it is
When the more diverse an ecosystem is so here the option b is selected i.e. the more similar the species will be.
What is an ecosystem?An ecosystem comprises of all type of organisms and the physical environment in which they interacted.
These biotic and abiotic components are connected together via the nutrient cycles and flow of energy.
So when the ecosystem is more diverse so the species should be more similar.
Hence, the option b is correct.

"Describe and explain how Mercury might be different if it had the same mass as Earth. *Consider the planet's composition"
Answer:This also means that Mercury's surface gravity is 3.7 m/s2, which is the equivalent of 38% of Earth's gravity (0.38 g). This means that if you weighed 100 kg (220 lbs) on Earth, you would weigh 38 kg (84 lbs) on Mercury.

The three basic economic questions societies face are (1) what goods and services to produce, (2) how to produce those goods and services, and (3) who will get them.
In one or two paragraphs, explain how supply and demand help societies determine their answers to these three questions. Be sure to provide an example of the effect of supply and demand on a society's answers.
please help
When supply is high is the people don’t want it as much. When the supply is low people most likely want It. Demand is just basically controlled by the people.
Supply and demand let's us know what needs to be more produced and what needs to be less produced. For example, the demand for a TV will be high, but the demand for paper might be low. So the company will produce more TVs and less paper because the Supply and demand tells them that the people want TVs. When supply is high the people don’t want it as much but the supply is low people most likely want It. Demand is just basically controlled by the people.
