The answer would be all of the above.
Answer:
A. much of the variation in individuals of a population is heritable
Explanation:
Charles Darwin is a scientist well known for his development of the concept of evolution. Darwin was able to deduce that the species of a population have a common ancestor and that as time passes there is a modification in the characteristics of these species that makes it easier for them to adapt to their environments. These traits that were inherited from past descendants, were helpful traits that made it possible for their own descendants to be able to survive better than their peers. He noted that there were limited resources for survival, therefore it was a case of the survival of the fittest.
Natural selection was the term used by him to describe how species of a population survived over time. Members of a population had varied traits that enabled them to survive. For example, the descendants of an ancestor could have slightly different shapes, colors, sizes, and other features but still maintain traceable heritable traits.
The correct answer is - B. The number and type of plants in an ecosystem determines the number and type of consumers that can live there.
The plants are producers. They are the basis of the ecosystems on Earth. By consuming the plants, the consumers are able to survive and thrive, thus the food chain develops further up to the predators that are consuming other consumers.
The number of plants and the type of plants determines what type and how many species of consumers can live somewhere. The more plants there are, the more food for the consumers, thus there will be more consumers. The higher the diversification of the plants, the higher the diversification of the consumers will be too, as every plant is unique and specialization for consuming it is needed, thus the consumers will evolve into new species in accordance to the food source.
They interact with light to absorb only certain wavelengths, pigments are useful to plants and other Autotrophs, organisms which makes their own food using photosynthesis. in plants,algae,and Cyanobacteria, pigments are the means by which energy of sunlight is captured by photosynthesis.
