<span>Simple.
All of the millions of different life forms (the diversity of life) have come about by natural selection, whereby random mutations in the genes have either succeeded or failed.
But all life can be traced back to a common single-celled origin. Thus we have the unity of life where we (possibly) share more than 50 % of our DNA with a crocodile.eg:analogous organs, homologous organs.</span>
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.

If I remember correctly, there are two main types of transport—passive and active. Passive transport does not require energy or ATP, whereas active transport does.
Types of passive transport include diffusion and osmosis, both of which involve moving down a concentration gradient and thus not requiring energy.
Active transport moves up the concentration gradient and does require energy.
Perhaps someone who has taken bio within the last several years can correct anything I might have misstated here.
