Q: In type 3 functional response, what mechanisms may be responsible for
In type 3 functional response, what mechanisms may be responsible for low rates of food intake—compared to type 1 and type 2 functional response—at low food densities?
See AnswerQ: Why are plants such as mosses living in the understory of a
Why are plants such as mosses living in the understory of a dense forest, which show higher rates of photosynthesis at low irradiance, unable to live in environments where they are exposed to full sun...
