Question

What is Ecosystem????​

Answer 1

$\blue{ \Large{\boxed{ \tt{ \red{Answer : }}}}}$

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.

Answer 2

Answer:

Phloem is involved in the distribution of food to different parts of the plant. The transportation of food in phloem is an active process achieved by utilizing energy from ATP which helps in creating osmotic pressure that transports food against the gradient from the area of high concentration to low concentration.

So, the correct answer is option A.
