The very bottom one is it
Heat is then the by-product of the light energy from the Sun flowing through the biosphere. Organisms are inevitably dependent on sunlight to perform essential biological processes in order to sustain life. In the absence of this energy, all the organisms on Earth would die.
Can you give an explanation if this is a true/false question?
Answer:
Animal cells do not have cell wall whereas plant cell have cell wall. Animal cells contain small and numerous valcuoles whereas plant cell contain large and single vacuole.
The answer is Because they are able to adapt to different conditions.
The least specialized animals are those animals that can survive in a wide range of different environmental factors, unlike specialized animals which are very sensitive to changes. If environment changes suddenly and drastically, highly-specialized animals could not survive because those changes are beyond a range of different factors that affects them. The least specialized animals could adapt to different conditions. For example, one species (specialized) lives in a temperature of 20-25°C. The other species (the least specialized) lives in a range of temperature 5-50°C.
If temperature changes drastically from 22°C to 10°C, the specialized species could not survive and the least specialized would just adapt to those conditions.
