Answer:
This situation might happen depending on the ecosystem that it takes place in.
Explanation:
For example, in one ecosystem, where there are no serious predators trying to get the coyotes, they could be in a higher level because there is no immediate danger to them. However, in another ecosystem where there are predators trying to hunt them, they would be in a lower level because there, they are not at the top of the food web. Basically, it all depends on the ecosystem.

The answer to this is C because humans don't have cell walls and if you are looking at an onion it has a cell wall because it is a plant.
Answer: I would say D)
Explanation:Phytoplankton are the autotrophic components of the plankton community and a key part of oceans, seas and freshwater basin ecosystems. This is the least ddt and is concentrated.
Answer:
1. interactions
2. environment
3. sun
4. photosynthesis
5. chemical
6. producers
7. food
8. energy
9. organisms
10. herbivores
10. first
12. Heterotrophs
13. second
Explanation:
An ecosystem consists of a community of living organisms
interacting with each other and the environment. The source of energy that fuels most ecosystems is the sun. Plants use the Sun’s energy to produce food in a process called photosynthesis.
Organisms that use energy from the Sun or energy stored in chemical compounds to produce their own nutrients are called autotrophs. They are also called producers because most other organisms depend on autotrophs for food and energy. Heterotrophic organisms that can’t make their own food may obtain nutrients by eating other organisms. A heterotroph that feeds only on plants is called an herbivore. Herbivores are also called first order heterotrophs. Heterotrophs that feed on other herbivores are second order heterotrophs.
A catalyst increase a chemical reaction, therefore making the answer B. Promotes a chemical reaction.
