Which of the following descriptions about the organization
of an ecosystem is correct? *

The description which is correct is:

Species make up populations which makes up communities.

Explanation:

In biology, species can be described as organisms which can interbreed to form fertile offsprings. Members of a species share many common characteristics. Example of species includes all human beings on earth.

In biology, a population can be described as the number of organisms of a species which are living together in a habitat at a particular time. These organisms have the capability to interbreed and produce fertile offspring.

The organisms present in different populations in an area at a particular time make up a community. For example, a population of birds, a population of insects, a population of plants that live in a certain area at a particular time make up a community.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
