Question

An organism's "trophic level" refers to _____. An organism's "trophic level" refers to _____. its position in the food chain where it lives the intensity of its competition with other species whether it is early or late in ecological succession the rate at which it uses energy

Answer 1

An organism's trophic level indicates its position on the food chain, starting with producers and moving up to primary, secondary, and tertiary consumers. The ecological pyramid demonstrates the decrease in biomass and energy at higher trophic levels, with only 10 percent of energy typically passed on to the next level.

Step-by-step explanation:

An organism's trophic level refers to its position in the food chain or food web. The various trophic levels start with producers at the first level, followed by primary consumers, secondary consumers, and tertiary consumers. The concept of the ecological pyramid, also known as the Eltonian pyramid, illustrates the cumulative effect of energy transfer through these levels, with diminishing quantities of biomass and energy as one ascends from producers at the base to apex predators at the top.

Only about 10 percent of the energy is transferred from one trophic level to the next, with the rest being used up or lost to the environment as heat. Consequently, there are generally fewer organisms and less biomass at higher trophic levels. This decrease is visually represented by the ecological pyramid shape, where the base is wide with producers and narrows at each subsequent level due to decreased energy availability.

Answer 2

Answer: Its position in the food chain

Explanation: The trophic level of an organism is a position of an organism in a food chain. It is a step in the ecosystem, that is, in the nutrient series, it should be said that there are several steps, so based on which step this organism is located in ecosystem, is determined the position of that organism in the ecosystem, i.e in the food chain. So you can say that it is the position of an organism in the food chain based on what step is involved. The first trophic level is the level with primary producers and these are plants, then herbivores, and carnivores, while levels four and five are predators, that is, top predators. The point is that the most capable "organisms" are predators at the top of the chain.

In addition to these, there are so-called separate trophic levels and there are so-called decomposers, i.e bacteria and other micro-organisms that decompose dead animals and waste, and from this they create fertile soil for the plant growth as a first step in the chain, but other producers can use it, too.
