Question

heterotrophic (parasitic) plants occupy which trophic level in the food chain? why?

Answer 1

Trophic level is an organisms positionin a food chain (or food web), and describes the way energy is obtained. ... As producers who make their own energy, they are known as autotroph. Hetertrophs that eat plants(herbivores) are in second trophic level, and carnivores follow.I hope its help u

Answer 2

First trophic level. The plants in this image, and the algae and phytoplankton in the lake, are primary producers. They take nutrients from the soil or the water, and manufacture their own food by photosynthesis, using energy from the sun.

The trophic level of an organism is the position it occupies in a food chain. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain. A food chain starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way flow or a food "web". Ecological communities with higher biodiversity form more complex trophic paths.
The word trophic derives from the Greekτροφή (trophē) referring to food or nourishment.[1]
