Answer:
Fossils provide evidence about life on Earth that currently extinct. Through fossils, we've discovered several species of animals and plants that previously existed. We also learn how life on Earth changed throughout the years. Fossils found in younger rocks look like animals and plants that are living today. Fossils in older rocks look less like the current living animals and plants. Some fossils found look either more or less like current species we know today.
Explanation:
Abiotic: the sunlight and water.
Biotic: Plants and insects
Explanation:
Plants such as cactuses can absorb and conserve water in their roots and use the sunlight to grow taller
Insects such as Desert beetles can trap moisture in their thick exoskeletons so they are parched or burned by the sun. They sometimes bury themselves deep in the sand where it's cooler.
The abiotic factors in the desert help the biotic factors survive
