write short note in energy pyramid with the diagram,define, point, explain and Definition
Answers
Explanation:
An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level. ... These are heterotrophs, meaning that they get food energy by consuming other organisms.
Answer:
An energy pyramid (sometimes called a trophic pyramid or an ecological pyramid) is a graphical representation, showing the flow of energy at each trophic level in an ecosystem.
The width of each bar represents the units of energy available within each trophic level; the height is always the same. The flow of energy moves through the layers of the energy pyramid from the bottom-up, and is gradually reduced as energy is used up by the organisms at each level
The base of the energy pyramid indicates the energy available within primary producers. Primary producers, also known as autotrophs, are organisms which create their own food by taking their energy from non-living sources of energy. In most cases, these are photosynthesizing plants, which use energy from the sun to create their own nutrition in the form of simple sugars, although there are exceptions such as deep sea organisms, which use chemical energy from hydrothermal vents. In this description we will focus on ecosystems that take energy from the sun.
All other levels in the energy pyramid consist of heterotrophs – organisms that obtain their nutrition from organic carbon, usually in the form of other plants and animals.
The second trophic level consists of primary consumers. These are the herbivores that feed solely on primary producers. The third and fourth levels are made up of secondary consumers and tertiary consumers. These are carnivores and omnivores, which can feed on any of the lower levels, although mainly consume organisms from the trophic level directly beneath them. The top layer of the energy pyramid contains apex predators. These are mostly carnivorous animals that have no natural predators.
