Example: Three birds loved to eat beetles especially the green (female) and the brown (male). But their favorites are the green beetles. Generations later, green beetles have been selected and brown beetles have increased in number. - What are the environmental changes that may cause organisms to adapt, migrate or die?

Example: Three birds loved to eat beetles especially the green (female) and the brown (male). But their favorites are the green beetles. Generations later, green beetles have been selected and brown beetles have increased in number.- What happens to organisms that cannot adapt to the changes that occur in their environment?
Imagine the environment of an ecosystem changes such that it floods more often. Which species would most likely increase in numbers in this new environment? a flightless bird species that makes its nest on the ground a tree species that is tolerant of excess water a mammal species that burrows underground an insect species that lives on the leaves of short bushes
Which of the following scenarios best explains how resource partitioning can lead to adaptive radiation? The lack of competition between individuals leads to better survival and reproduction rates. The utilization of different resources requires different adaptations, selecting for different traits. The lack of competition leads to a more balanced ecosystem, resulting in more offspring. There is no connection between adaptive radiation and the resource partitioning in nature.

How would an increase in grasshoppers affect the rabbit population? Using evidence from the food web,explain why it is called a food"web"
Which of the following statements is not true of an ecological niche?a. A niche includes the physical environment, such as climate and water availability.b. A niche includes predators and parasites.c. Niche overlap may help to drive evolution.d. Two species cannot have overlapping niches.
Example: Three birds loved to eat beetles especially the green (female) and the brown (male). But their favorites are the green beetles.

All populations become small before going extinct. Is small population size really a cause of extinction, or just something that happens as a result of other factors that cause extinction?
