question
How has the Gila Monster adapted to the breeding patterns of its prey the Gambel quail and desert cottontail rabbits?
answer
Because the Gila Monster feeds on the eggs/young of the Gambel's quail and desert cottontail, its principal food supply is only available for a limited period of time each year. The Gila Monster has therefore adapted to consume its entire yearly energy supply in a few meals in the spring. It stores much of its energy as fat in its tail so it can survive the rest of the year.

question
Explain the relationship between light intensity and the daily rhythm of flowers opening.
answer
Plants such as flowers often respond to abiotic environmental factors such as the length and intensity of light exposure. These factors help regulate daily rhythms such as flower opening and closing as well as seasonal rhythms like fruiting and seed formation.
question
Explain how water can be an abiotic environmental factor when it is essential to all life on earth.
answer
Even though water is essential to all life and is a part of all living organisms, water itself is not a living thing. Water by itself is abiotic, but both biotic and abiotic factors are critical to healthy environments.

question
Explain why echolocation is a superior adaptation for insectivorous bats rather than fruit bats.
answer
Insectivorous bats have to hunt small, fast moving flying insects while fruit bats need to search out stationary fruit trees and flowering bushes. The ability to track fast-moving targets in the air is far more valuable for insectivorous bats whose prey are trying to fly away from them and escape.

question
Compare the importance of both biotic and abiotic factors to an ecosystem.
answer
Both biotic and abiotic factors are critical components of an ecosystem. While an ecosystem cannot exist without the organisms living in it, factors such as sunlight and water are also critical because ultimately all organisms living on earth need water and light to survive.
