What else can I help you with?
Why does productivity diminish with increase trophic levels?
Due to poor trophic transfer efficiency, most energy is lost at higher trophic levels.
Why don't pollutants build up as you go up trophic levels?
Pollutants often bioaccumulate in organisms at lower trophic levels, but they can also become diluted as they move up the food chain. While some pollutants, particularly persistent organic pollutants, can biomagnify and increase in concentration at higher trophic levels, this is not the case for all pollutants. Additionally, energy transfer between trophic levels is inefficient, leading to fewer organisms at higher levels, which can limit the overall concentration of pollutants. Environmental processes, such as degradation and dilution, also help mitigate pollutant accumulation at higher trophic levels.
Feeding levels in an ecosystem are called?
The different levels in a food chain are known as trophic levels. There are multiple levels, starting at the bottom with autotrophs, mostly plants that make their own food, and ending with apex predators, that are at the top and have no predators of their own.
How many levels do trophic levels have?
Five
Number of trophic levels in ecological pyramid?
there can be any number of trophic levels, but usually 4-5
What trophic levels do armadillos belong to?
The trophic level is the level in the food chain that an animal occupies. The armadillo belongs to both the second and third trophic levels.
What meant by trophic levels?
answer
What relationship exists between trophic levels and food chain?
Trophic levels and food chains are connected in number of ways. Trophic levels show the energy transfer throughout the species in different food chains.
What determines how many trophic levels a rainforest ecosystem can support?
The number of trophic levels in a rainforest ecosystem is determined by energy availability and efficiency of energy transfer. Typically, rainforest ecosystems can support multiple trophic levels due to the high productivity of plants and diverse species interactions. Factors like nutrient availability, resource partitioning, and predator-prey dynamics also contribute to the number of trophic levels in a rainforest ecosystem.
Illustrate 4 tropical levels?
tropical levels or trophic levels?
What is the second trophic level in the food web?
The second trophic level in a food web consists of primary consumers, also known as herbivores. These organisms feed directly on producers, such as plants or algae, and are then consumed by predators at higher trophic levels.
What is called when each step in a food chain or web?
the steps are known as trophic levels as move down the levels energy from the organisms tends to be lost to the environment
