A mutualistic and A a decrease in the number of corals
They are all formed from data, predictions and observations.
Any characteristic, whether a physical trait, a behaviour, a physiological adaptation etc can make an organism more or less likely to survive in a particular environment.
A dark colour could help a rabbit survive if it lives in a dark forest, because predators can't see it so well, but it would be less likely to survive in the arctic, where the environment is all white and it would show up.
In terms of the characteristics, think about: does it help the organism get food? Does it help protect the organism from predators? If it does, that organism is more likely to survive, and pass the characteristic on to it's offspring. If a bacterium has a characteristic of not being killed by antibiotics, this will help it to survive and breed.
energy enters an ecosystem through photosynthesis. By feeding on plants and on one another, animals play an important role in the movement of the matter/energy though. they also influence the quantity of plant and biomass present. so the anwser is D, secondary consumers to tertiary consumers
Answer:
C
Explanation:
The globin of the RBC is broken down into constituent amino acids that can be reutilized by the phagocytic cells (this can occur in the spleen, liver and lymph node). The chains cannot be reused in their large form. The heme(iron) is transported by the blood to the bone marrow and is used to make new red blood cells.
