This is a major cause of biodiversity loss due to deforestation and habitat destruction.

What is human activity?

300

 These are nonliving factors in an ecosystem, such as sunlight or temperature.

What are abiotic factors?

300

 This element is essential for building DNA and proteins in living organisms.

What is nitrogen?

300

The four conditions for natural selection are overproduction, variation, heritability, and this.

What is differential survival/reproduction?

300

Structures that have a similar origin but may serve different functions, like a human arm and bat wing.

 What are homologous structures?

300

The maximum population size an ecosystem can sustain over time.

What is carrying capacity?

400

The term for when two species compete for the same limited resource.

What is competition?

400

 The movement of nitrogen through the atmosphere, soil, and organisms.

What is the nitrogen cycle?

400

A moth’s dark coloration increasing its survival during the Industrial Revolution is an example of this.

What is directional selection?

400

This type of evolutionary evidence compares embryonic development across species

What is embryology?

500

This concept describes how well an organism survives and reproduces in its environment

What is fitness?

500

DNA similarities across species, such as humans and chimpanzees sharing 98% of their DNA, fall under this type of evidence.

What is biochemical evidence?

500

 The term for actions to reduce human impact on the environment, such as habitat restoration or pollution control.
