1. The variety and variability of organisms is called ___________________________ . One of the benefits of this kind of variety includes ecosystem ( resilience / services / diversity / succession ) , which is the ability of an ecosystem system to recover after a disturbance. Other benefits of healthy ecosystems include ecosystem ( resilience / services / diversity / succession ) such as pollinating crops, regulating pests, and maintaining soil structure.

• biodiversity
• ecological succession
• population ecology
• symbiotic relationships

Mr. Rojas, a biology teacher, asks his class to evaluate two examples of changes to a pond ecosystem. The table summarizes the examples. Example

• the benefits provided by biodiversity within the pond ecosystem
• the ecosystem services that the pond provides
• the climax community that will result from secondary succession
• the resilience of the pond ecosystem to different types of changes

All healthy, highly productive ecosystems provide which of these essential ecosystem services that involve gases in the atmosphere?

• Increasing carbon dioxide levels in the atmosphere by the action of plants and animals.
• Removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms.
• Removing water vapor from the atmosphere and using it to support plant growth.
• Removing methane from the atmosphere and storing its carbon and hydrogen in the tissues of organisms.

Much of an ocean beach is covered in sand dunes and grasses. The homeowners along the beach propose to flatten out the dunes and remove the grasses, which would allow more visitors to use the beach for swimming and sunbathing. If the homeowners' plan is enacted, which is the most likely consequence?

• purer, less salty groundwater for the beach community
• more sea turtles laying eggs on the beachc. increased risk of erosion during storms
• an increase in the depth of beach sand
• increased risk of erosion during storms

Ecologists in California are concerned about the effects of urbanization and the spread of invasive species on the biodiversity of natural areas. What measures might they take to help conserve biodiversity? Select all that apply.

• Indicator species monitoring
• Captive breeding programs
• Preserving ecosystems
• Protecting biodiversity hotspots
