Ecological Pyramids.
it when the food web and food chain
food chains and food webs are necessary as they maintain the ecological balance
Pyramids of energy show the relative amount of energy available at each trophic level of a food chain or food web. (:
Producers, such as plants or algae, are at the base of all ecological pyramids. They convert sunlight into energy through photosynthesis, which then flows through the food chain to support all other organisms in the ecosystem.
I'm not sure, I have this for homework this week though XD
The concept is often associated with descriptions of food chains and food webs (Food Chains and Food Webs in an Ecosystem, Food Chain and Food Web Book Reviews). An ecological pyramid is an illustration of the reduction in energy as you move through each feeding (trophic) level in an ecosystem. The base of the pyramid is large since the ecosystem's energy factories (the producers) are converting solar energy into chemical energy via photosynthesis. A food chain can also depict a reduction in energy at each feeding level if the arrows, drawn between the different levels, continue to be reduced in size.
They show mainly the same info: how energy flows through predation. Food chains show a specific path in which energy flows, food webs show many different variations of paths, with many different species involved, while food pyramids show the same thing as a food chain, but in a pyramid box.
Ecological pyramids show the relative amount of energy or biomass stored at each trophic level in a food web. They illustrate the decrease in energy or biomass as it moves up the trophic levels due to inefficiencies in energy transfer.
True. Ecological pyramids illustrate the flow of energy or matter through trophic levels in a food web by arranging organisms based on their position in the food chain. Generally, the lower the trophic level, the greater the amount of energy or biomass that can be supported.
Producer organisms are at the base of all ecological pyramids. They are the only organisms which can make their own food (autotrophs). The overwhelming majority of them are green plants and single celled organisms which photosynthesise, though a few are chemautotrophs, that is they get energy from inorganic materials.
Several food chains combined is known as a food web, and this is a prominent feature in an ecosystem as it shows the relationship between different animals and it shows how all the species exist in their community.
