Iguanas and tortoises eat leaves, fruits, and flowers, relying on each as important seasonal food sources.
Birds eat berries and seeds, dispersing the seeds in their droppings as they fly.
Hummingbirds drink the nectar of flowers, and they will defend their territory in order to secure their food supply.
Insects like bees and butterflies drink nectar, carrying pollen from one flower to another.

Territorial behavior is the animal of the same kind, but of the opposite sex. Courtship behavior is the production of offspring.

Fig trees can only be pollinated by the fig wasp. What would happen to the fig wasp population if the tree population became diseased and started dying off.
*
1 point
The wasps would find another food source.
Fig tree seedlings would start to regrow to sustain the wasp population.
The wasp population would decrease to accommodate the reduced tree population.
The wasp population would not be affected as long as some of the fig trees survived.
The wasp population would decrease to accommodate the reduced tree population.

A student is analyzing the following data to compare the relationship between wading bird's nests and rainfall rates. She finds the following information:
-Wading birds feed primarily on fish
-Fewer nests are observed in dry years than in wet years
What inference could you make about the relationship between wading bird's reproductive success and the water depth in the Everglades?
*
1 point
Water depth does not affect wading birds’ access to food and thus does not affect wading birds’ reproductive success.ion 1
Water depth likely affects wading birds’ access to food and thus affects wading birds’ reproductive success.
Water depth does not affect wading birds’ access to food but does affect wading birds’ reproductive success.
Water depth likely affects wading birds’ access to food, but this does not affect wading birds’ reproductive success.
Water depth likely affects wading birds’ access to food and thus affects wading birds’ reproductive success.
Ants and elephants both live in groups instead of by themselves. They each live in groups for survival, but for different reasons.
Which would accurately explain the reason they live in groups as they do?

Consider this scenario:
*The yucca plant depends on the yucca moth as its only pollinator.
*The yucca moth caterpillar feeds only on the yucca plant.
*A large population of bats moved into the area and starts overfeeding on the yucca moth and caterpillar.
Answer the following questions in 4-5 sentences.
1) (2 pts) What would happen to the Yucca moth population? Explain why this would happen.
2) (2 pts) What would happen to the Yucca plant population? Explain why this would happen.
1) The yucca moth population would decrease because of the sudden increase in predation by the large population of bats. Bats would feed on the adult moths, and the decrease in adult moths will lead to a decrease in pollination, causing the yucca plant to produce fewer seeds. As the moth population decreases, the plant's population will decrease as well.
2) The Yucca plant population will decrease over time if the yucca moth population continues to decline. The yucca plant relies solely on the yucca moth for its pollination and reproduction process. When the number of Yucca moths decreases, the rate of pollination decreases, and fewer seeds are produced. As a result, fewer Yucca plants are produced in the area. Ultimately, the decrease in the Yucca population will cause a ripple effect on the ecosystem as other animals in the area depend on the plant as a primary food source.
