Turtles look for quiet, dark beach areas on which to nest. Tourists on the beaches may bother the turtles. Also, the lights from hotels and businesses discourage females from nesting at night. If a female doesn't find a safe place to nest, she may lay her eggs in an unprotected area or in the ocean. In these cases, many of the hatchlings will not survive.


What other factor may prevent the turtles from finding safe places to nest?
Salt grasses growing on the beach
Wind blowing sand to form dunes
Turning off flashlights and lanterns
Pets running loose on the beach
Which of the following food chains shows the correct flow of energy between organisms?
Consumers → decomposers → producers
Decomposers → producers → consumers
Consumers → producers  → decomposers
Producers → consumers → decomposers
A mouse population became ill and decreased in numbers.  What will most likely happen to the owl population, which depends on mice for part of its food source?
The owl population will decrease because there is less food for it to eat.
The owl population will eat other animals, and its numbers will not change.
The owl population will increase because it no longer competes with the mice.
The owl population will stay the same as it eats food that the mice population would have eaten.
Organisms interact with living and non-living components in their environments daily. Which organisms are interacting with non-living components in their environments?

It is a consumer because it uses other organisms for energy.
It is a producer because it depends on plants for energy.

Axis deer are an invasive species of deer found in Texas. There are about 125,000 axis deer in Texas. Axis deer eat grasses, flowering plants, and shrubs. The diet and habitat of axis deer are often the same as those of other animals native to Texas.

Based on this information, how do axis deer most likely affect Texas ecosystems?
They cause populations of native plants to increase.
They overgraze the land, which causes soil erosion to increase.
They cause the predators of native animals to move to new locations.
They increase the availability of food, which causes an increase in herbivore populations.
Using the information in the table, which butterfly species would be least affected by a drought that reduces the amount of available nectar?
Pearl Crescent
Gulf Fritillary
Question Mark
Common Buckeye
