Answer:
there are four trophic levels first are producers then primary consumers then secondary consumers then teritary consumers
Explanation:
grass - grasshopper - frog - snake - eagle is a simple food chain
Phloem is the food conducting tissue that has a two-way flow.
Explanation:
Plants prepare food on their own and plants also have conductive cells that carry out transportation process. Plants are divided into two types based on their conductive system i.) vascular plants ii.) non vascular plants.
Vascular plants are those plants which have special conductive cells called phloem and xylem.
Xylem transports water from roots of the plants to other parts of plants and also provides mechanical support to plant. It is uni-directional.
Phloem is the food conducting tissue that transports food to plant and also have bi-directional movement.
energy enters an ecosystem through photosynthesis. By feeding on plants and on one another, animals play an important role in the movement of the matter/energy though. they also influence the quantity of plant and biomass present. so the anwser is D, secondary consumers to tertiary consumers
