Answer:
Species evenness refers to how close in numbers each species in an environment is.
Explanation: For example, let's say there are 15 elephants, 60 zebras and 5 lions on our first sample. The sample from the second states 35 elephants, 25 zebras and 20 lions. The total of both sample 1 and sample 2 become 80. Sample 2 is relatively more evenness than sample 1 . This is because the total number of animals in the sample is quite evenly distributed between the 2 samples. This environment is not very even though. Species richness is a measure of the number of different kinds of organisms present in a particular area. Evenness compares the similarity of the population size of each of the species present as I mentioned above.

All this combined = rise in fatalities which = less reproduction = lower population
Heart and lungs works hand in hand. Not only that they are close to each other but they also work to make sure that body gets enough oxygen that it needs to live. It is the heart that pumps blood through the body it passes through the lungs. then it is the job of the lungs to supply oxygen together with the blood that heart pumps.
