The answer is commensalism.
Commensalism is a relationship between two
species in which only one of them has benefit, and the other one is not
affected.
In this relationship, frogs benefit from this relationship. They get water and shelter from the Bromeliad. The Bromeliad <span>does not gain or lose anything in the relationship, so it is not affected anyway. Thus, the relationship between frogs and the Bromeliad is an example of commensalism.</span>
Answer:
The correct option is<em> b. at each step, energy is lost from the system</em>
Explanation:
The amount of energy that travels from one trophic level to another is known to declines at each level. Infact, only 10% of the energy travels from one trophic level to another.
This is because most of the energy is lost by the organisms at each trophic level. It is due to the metabolic processes which occur in the organisms of each trophic level and most of the energy is lost as heat.
