Question

In an ecosystem what represents a stepwise transfer of energy through food?​

Answer 1

Answer:

Food Chains

REASON :

A food chain the transference of energy between organisms through consumption, in this case, the rabbit is eating grass and the fox is eating the rabbit. The initial energy source is found in the plant. The plant uses initial energy from the sun to convert into chemical energy via photosynthesis.

Answer 2

Answer:

In each ecosystem, it is energy, that enables organisms to live. This energy mainly comes from one original source: photosynthesis. The plants in the ecosystem use this solar energy to produce carbohydrates which are then consumed by other organisms: transferring the energy.

Not all of the energy from sunlight, however, is used by the plants solely as energy; they are far from efficient. A lot of sunlight misses the plant, is in the wrong wavelength or lost in the inefficiencies of photosynthesis. We use the term gross primary production to refer to the total energy in the molecules of the plant; net primary production is the surplus energy not used by the plant itself.

At each level of the food chain energy is lost because it is used by the organism itself for respiration. This limits the number of steps there can be in a food chain.
