In a food web, each depends on the trophic level below it for energy

a) consumer
b) decomposer
c) detritivore
d) producer

The correct answer would be A) consumers.

Consumers are the organisms which depend on other organisms for their energy needs.

In a food chain, the consumer consumes other organisms present on lower trophic level.

For example, cow, deer, et cetera (herbivore) are the primary consumers which consume autotrophs or green plants which are present on lowest trophic level.

Similarly, lion, tiger, et cetera are the highest consumers which feed on organisms present on lower trophic levels such as cow, deer, giraffe et cetera.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
