organisms can be either producers or consumers in terms of energy flow through an ecosystem. producers convert energy from the environment into carbon bonds, such as those found in the sugar glucose. other producers includebacteria living around deep-sea vents.
the low rate of energy transfer between trophic levels makes decomposers generally more important than producers in terms of energy flow. decomposers process large amounts of organic material and return nutrients to the ecosystem in inorganic form, which are then taken up again by primary producers .
a pattern of energy flow through the organisms that live in any ecosystem can be observed. producers, such as a tree, algae make their own food and begin this cycle. the producers are then eaten by primary consumers that cannot produce their own food, such as a giraffe. they eat the primary consumers . producers bring energyfrom nonliving sources into the community. primary consumers eat th eproducers, which makes them herbivores in most communities .
algae is protist ,carry out ,photosynthesis ,lives in ponds & oceanfound in fresh and salt water environments .can live on rocks, trees, and in soils with enough moisture.can carry on photosynthesis – produce large amount of oxygen .
population growth is difficult to predict because unforeseen events can alter birth rates, death rates, migration, or the resource limits on population growth
such policies could have a significant effect on global fertility rates.
