Answer:A population is a group of living organisms of the same kind living in the same place at the same time. All of the plant and animal populations living in a habitat interact and form a community. The community of living (biotic) things interacts with the nonliving (abiotic) world around it to form the ecosystem.

Answer:
During the industrial revolution in England, the soot from the coal burning factories started dominating the environment. The trees were also darkened as a result and the light-bodies moths that were able to blend with the light-coloured lichens and tree barks were in danger due to their predation by the birds. This lead to the rapid decrease in the light-colored moths. As a result, the moths got adapted to the blackened trees with their transformation into dark-coloured moths which Increased rapidly. This was because the allele for the dark-bodied moths is dominant and the allele for the light-bodied moths is recessive. Since birds would find and eat the light-bodied moths, dark-coloured moths increased as a result of natural selection. Thus, these moths with a favorable adaptation to the change in the environment were selected and they reproduced new offspring.

Answer:
Idealized pyramid of net production uses the typical values of 1% for the conversion of sunlight energy to net primary production and 10% for trophic efficiency.
Explanation:
in real ecosystems, trophic efficiencies usually vary from about 5% to about 20%. As a result, net production diagrams for ecosystems have a pyramid shape. Two key factors explain why trophic efficiencies are relatively low, and thus why net production diagrams are shaped like pyramids. First, not all the organisms at one trophic level are eaten by organisms at the next trophic level. For example, not every plant is eaten by herbivores, and not every herbivore is eaten by carnivores. Second, because of the bioenergetics of animals, not all the food an animal eats is converted to new biomass. Significant amounts of energy are lost in feces, used in cellular respiration, and lost to the environment as heat.
C as more energy requires more work for the body
