Ecosystem

An ecosystem contains many organisms. Three of the four parts of a ecosystem are made of cells. Consumers, producers, and decomposers are all made of cells, because they are alive. Abiotic factors are not alive, so they contain no cells. Water, sunlight, and air are all abiotic factors, so they contain no cells. Lions, shellfish, shrimp, elephants, birds, and humans are all consumers, but they live in different places, so their cells are affected by their environment, for instance, fish, which live in the sea, have scales, whereas birds, which fly, all have feathers. And bugs, which have an exoskeleton, are different from dogs, which have an internal skeleton. The size, place of an animal on it’s food chain, and its natural environment play big parts in its cellular structure. Worms, who are decomposers, have no skeleton whatsoever, allowing them to move through tight spaces easily, but humans require their skeleton to move and keep them relatively organized (organ-wise). All producers have cells which absorb sunlight and carbon, and combine it with water to make energy. They also contain vacuoles, which allow them to keep their shape, by providing pressure. A feature of cells that play a role in the environment is cellular respiration. It coinsides perfectly with photosynthesis, in that the wastes of one create the ingridients of the other, which creates balance in an ecosystem. An ecosystem with just plant cells would fall apart, because there is nothing to balance them out.
