According to natural selection, skeletal changes occur gradually as individuals adapt to their environment and pass these changes on to their descendants.
We can arrive at this answer because:
As a result, the skeletal modification takes place gradually in the population of individuals as new members are born and old members die.

Answer:
An ecological pyramid is a graphical representation of the distribution of the biomass to different organisms in successive trophic levels. The energy is being lost by 10% in every higher trophic level, when one organism is consumed by another organism in a food chain. Therefore, the number of trophic levels in a pyramid will be limited.
Answer: A species includes all organisms that can mate with one another to produce sexually fertile offspring. No individual organism lives forever. Therefore, reproduction is essential to the continuation of every species. Some organisms reproduce asexually and other organisms reproduce sexually.
Explanation:
The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.
Snow covers tundra lands for the majority of the year, but summer provides bursts of wildflowers.
The small plants of the tundra employ dormant strategies, producing seeds only occasionally, turning with the sun to absorb energy, and growing protective coverings.
The ability to build subterranean insulated tunnels as well as heavy winter coats, seasonal color-changing camouflage, and efficient body shapes have all been developed by animals that live in the Arctic tundra.
Therefore, The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.

Answer: Plants and animals are able to survive in the tundra because they have adaptations that allow them to thrive in the harsh conditions of the Arctic and sub-Arctic regions. These adaptations include thick fur or feathers to insulate against the cold, small body size to minimize heat loss, and the ability to store food and nutrients during the short growing season. Additionally, many tundra plants have shallow roots that can absorb nutrients quickly when they are available, and some have developed the ability to photosynthesize at low temperatures and with minimal sunlight.
