Answer:
The cell wall is the outside layer and the cell membrane is the inner layer. Cell walls are made of cellulose and lignin, while cell membranes contain phospholipids. Cell walls are made of cellulose and cell membranes are made of proteins. The cell wall is the rigid structure the surrounds the cell and the cell membrane is flexible and skin like and surrounds the cytoplasm.

If producers were removed from an ecosystem, it would fall apart. Producers are the organisms at the bottom of the food chain, which produce glucose and nutrients for consumers. If producers were removed from an ecosystem, the consumers would have no nutrients and die, causing their predators to die, and so on.
A lot of the energy from photosynthesis flows out as heat.
^answer
When energy is being transported or flowed through the ecosystem most of the heat is lost.

The answer is <span>A. Meiosis: It increases genetic variation, which helps ensure the species will survive.
Meiosis increases genetic variation. This means there is a great variety of genotypes among the population. Hence, there are organisms able to survive in a wider range of temperature. If </span><span>there were drastic changes in temperature in an ecosystem, some of the organisms will survive because their genotype allows them to live in such conditions. If there were no variety thanks to meiosis, all of the organisms would die. And that is not beneficial to a species.
Imagine on the other hand that mitosis occurred. Mitosis does not provide a variety of genotypes and all of the organism will be the same. </span><span>If there were drastic changes in temperature in an ecosystem, all of the organisms would die because all of them could respond to the change in the same way.</span>
