Unit 5 - 8 AP Biology Insta-Review

Front

What is crossing over?

Back

The exchange of genetic material between homologous chromosomes during Prophase I of meiosis, leading to genetic variation.

Front

When does crossing over take place?

Back

Prophase I.

Front

What defines a population in ecology?

Back

A group of individuals of the same species that live in the same area and interbreed.

Front

What are density independent factors?

Back

Factors that affect population growth regardless of population size, such as natural disasters.

Front

How do density independent factors affect growth rate?

Back

As population size increases, growth rate stays the same.

Front

What happens to producers if a secondary consumer population decreases?

Back

Producers would likely increase due to reduced grazing pressure.

Front

Where do chemosynthetic organisms get their energy?

Back

From inorganic molecules, such as hydrogen sulfide.

Front

What is the role of producers in an ecosystem?

Back

Producers convert solar or chemical energy into organic matter through photosynthesis or chemosynthesis.

Front

What is the difference between a population and a community?

Back

A population consists of individuals of the same species, while a community includes all the different species living in a particular area.

Front

What is carrying capacity?

Back

The maximum population size that an environment can sustain indefinitely without being degraded.
