A. food pyramid
B. food chain
C. food web
D. food log
Hello!
Let's look at some definitions!
A food pyramid is levels of predators, in an pyramid shape to show the successive.
That does not match the definition your question provided, so we can move on.
A food chain is a series of animals who depend on each other for food/buisness.
Again, it does not match, this is a series, not an entire ecosystem.
A food web is a connection of food chains, which show the entire relationships of an ecosystem.
This definition is fairly close to the listed definition, lets keep this in mind.
A food log is a chart of what you eat each day.
Trick answer! This has nothing to do with the subject.

Hint: think about parents passing on alleles and dominant vs recessive. ANSWER ASAP FOR BRAINLEIST
Answer:
You have a trait (plant color) and you have two possible outcomes for it (purple and white). You know that some alleles for white were present in one of the parent plants, so you know they must be present in the offspring too. But they're expression is covered up by the purple alleles from the other plant, so you know that purple is dominant to white.
