The Couch’s spadefoot lives in Texas and has the characteristics listed below.
Their pupils are vertical slits.
Adults have mottled brown back and light-colored bellies.
Their eggs and tadpoles develop quickly in the temporary ponds forming after rain.
Adults live in holes they dig using special “spades” on their rear feet.
Adults eat insects and spiders.

Scientists studying aquatic plants notice flooding often leads to a decrease in their rate of photosynthesis. Flooding causes more sediment to be suspended in the water thereby decreasing the amount of light reaching the plants. Why does a decreased rate of photosynthesis lead to a decrease in a plant population?
Less water is available for absorption.
Less tissue is available for plant growth.
Less energy is available for reproduction.
Less soil is available for leaf development.
