Answer:
d.organisms from the past
Explanation:
Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet's history. They can also help scientists reconstruct the evolutionary histories of present-day species.
Constant speed would have a straight and diagonal line either facing upwards or downwards in the graph. This is because speed is displacement divided by time, which becomes the slope of the graph.
The virus introduced to the island in 1982 that reduced the wolf population is an example of a density dependent factor.
In ecology, a density-dependent factor, also known as a regulatory factor, is any force that modifies the size of a population of living creatures in response to population density.
Because of their propensity to maintain population densities, density-dependent factors are also known as regulating factors.
Population size and a density-dependent factor's level of control are correlated, therefore an increase in population will increase the influence of the limitation. Density-dependent factors involve biotic factors such as availability of food , predation, competition, parasitism and disease.
