APES Semester Exam Review

Front

What terrestrial biome has the highest net primary productivity?

Back

Tropical Rain Forest

Front

What type of feedback is demonstrated by the melting of polar ice caps due to increased Earth's temperature?

Back

Positive feedback

Front

According to the theory of island biogeography, which type of island is likely to have the highest number of species?

Back

Large island, close to mainland

Front

What do negative feedback loops do?

Back

Prevent small changes from getting larger

Front

What is the zone where a stable healthy population survives called?

Back

Optimal range

Front

Define net primary productivity (NPP).

Back

The rate at which all the autotrophs in an ecosystem produce net useful chemical energy.

Front

What is the significance of albedo in climate change?

Back

Albedo refers to the reflectivity of Earth's surface; lower albedo leads to more absorption of heat and contributes to warming.

Front

Explain the concept of island biogeography.

Back

It studies the ecological relationships and distribution of species on islands, focusing on factors like size and distance from the mainland.

Front

What is the difference between positive and negative feedback loops in ecological systems?

Back

Positive feedback amplifies changes, while negative feedback counteracts changes to maintain stability.

Front

What factors contribute to the optimal range for a species?

Back

Environmental conditions such as temperature, food availability, and habitat.
