Autotrophs are organisms which synthesis food (glucose) as product and release oxygen as by-product in the process of photosynthesis. In the process they use carbon dioxide, water in presence of sunlight. Examples of autotrophs are green plants, algae, blue green algae. The heterotrophs use glucose and oxygen produced by autotrophs. In turn, heterotrophs release carbon dioxide during cellular respiration which is used by autotrophs. In this way autotrophs and heterotrophs benefit each other.
Mutualism, commensalism and parasitism
Yes. Think of it as a skeletal structure for worms. It's basically what allows them to move.
Answer:
-Climate is the usual temperature, weather, humidity, wind, etc of a part of the earth. (The United States Climate is generally a cold winter and hot summer.).
-Climate change can effect an ecosystem because if an ecosystem has been used to this specific climate for years and it gets switch all the organism that have acclimated to that climate has a chance or death. (Like Global Warming, if the earth warms up from its usual temperature everywhere species will have to move and forced out of there homes. Some will even become extinct because of it.)
