What is an explanation of why producers are always found at the lowest trophic level?

Explanation: The reason why producers are always found at the lowest trophic level is because there is no need for them to consume other organisms (or living things) to be able to get their energy. In other words, they do not need to consume living things to produce energy.

What is a trophic level who is the lowest trophic level the highest?

The trophic level of an organism is the number of steps it is from the start of the chain. A food web 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.

Why are the number of trophic levels limited?

In a food chain, only 10% of the total amount of energy is passed on to the next trophic level from the previous trophic level. As we move higher up in the food chain the amount of energy diminishes to a level at which it cannot sustain any trophic level, thereby limiting the number of trophic levels.

Is the number of trophic levels limited?

The number of trophic levels in an ecological energy pyramid is most definitely limited. As one increases in trophic level, there is less and less energy available.

What trophic level has the most organisms?

The first trophic level contains the greatest number of organisms and is comprised mainly of plants. The organisms in this layer are called primary producers because they get their energy from an abiotic source. Most primary producers get their energy directly from the sun

What is meant by food chain the number of trophic levels?

Food chain is a simple representation of energy flow in nature. In a food chain the number of trophic levels are limited to 4 – 5. This is because according to 10% law of energy transfer only 10% of energy passes from one trophic level to next. Thus the amount of energy decreases with successive trophic levels.

What is meant by food chain?

Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. In a predator chain, a plant-eating animal is eaten by a flesh-eating animal.

What happens if all the primary consumers die in a food chain of an ecosystem?

If primary consumers are removed from the food chain the secondary consumers dont have anything to eat, this will disappear. As a side effect the tertiary consumers wont have anything to eat and then they will disappear. This will result in the collapse of the the ecological system

What happens if you remove the primary consumer?

Explanation: Primary consumers are the only organisms that are able to “harvest” the energy stored in producers. Without the primary consumers there would be no source of energy for carnivores or secondary consumers so no secondary consumers would exist in that ecosystem

Are the main support for every food chain?

All food chains start with energy from the sun. This energy is captured by plants. Thus the living part of a food chain always starts with plant life and ends with an animal. Plants are called producers because they are able to use light energy from the sun to produce food (sugar) from carbon dioxide and water.
