Answers
Explanation:
8. Cold-blooded animals are the animals that are not capable of regulating their body's temperature according to the temperature of the surrounding. Warm-blooded animals are the animals that are capable of maintaining a nearly constant body temperature irrespective of the temperature of the environment.
9. Sunlight, air, soil, rock, minerals, water, etc. are all biotic factors. ... Air also interacts with plants, helping them grow by providing a source of carbon (CO2) and other nutrients. In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients.
10. One special animal that is commonly found in the soil is earthworms. Earthworms are “nature's plow”, active in turning, mixing, and aerating the soil. The burrows of earthworms act like large pores that allow water from rain and melting snow to infiltrate into the soil, instead of running off and causing erosion.
