Characteristics of Populations and Biodiversity

In the Earthworm Lab, touching the worm caused it to move. This is an example of what process?

• Growth and development

• Reproduction

• Stimulus and Response

A group of organisms of the same species that live in the same area.

• Population

• Community

• Ecosystem

This growth occurs when individuals of populations reproduce at a constant rate. It is J-shaped.

• 1. Exponential growth

• 1. Logistical growth

• Carrying Capacity

This growth occurs as resources become less available, the population slows or stops.

It is S-shaped.

• Exponential growth

• Logistical growth

• Extinction

NGSS.MS-LS2-4

The number of organisms of one species that can be supported in an environment.

• Carrying Capacity

• Limiting Factor

• Ecological Succession

Tags

NGSS.MS-LS2-1

The total of all the variety of organisms in a specific area:

• Population

• Biodiversity

• Habitat

Tags

NGSS.MS-LS2-5

This occurs when a species disappears from all or part of its range:

• Endangered species

• 1. Threatened species

• 1. Extinction

Tags

NGSS.MS-LS4-1

Species whose population size is declining and losing genetic diversity.

• Threatened species

• Endangered Species

• 1. Invasive species

NGSS.MS-LS2-5

NGSS.MS-LS4-4

Species that are introduced to new habitats that lack parasites or predators for population control.

For example, a cane toad.

• 1. Endangered species

• 1. Invasive species

• 1. Predator species

Land development separates ecosystems into pieces cutting off species from their habitat

• Habitat Fragmentation

• Deforestation

• Habitat Loss
