Unit 5: Ecology

Front

What is the relationship between carbon dioxide concentrations and temperatures based on historical data?

Back

As carbon dioxide concentrations increase, temperatures increase.

Front

What percentage of energy from producers is passed to herbivores in an energy pyramid?

Back

10%.

Front

What is habitat fragmentation?

Back

Habitat fragmentation is the process where large habitats are broken into smaller, isolated patches, affecting biodiversity.

Front

What components make up an ecosystem?

Back

An ecosystem contains living and non-living components.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize uninhabited areas, such as lichens and mosses.

Front

Define biodiversity.

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem.

Front

What is the significance of the energy pyramid in ecology?

Back

The energy pyramid illustrates the flow of energy through different trophic levels in an ecosystem.

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread widely in a new habitat, often harming native species.

Front

What is overexploitation in the context of biodiversity?

Back

Overexploitation refers to the unsustainable use of natural resources, leading to species decline.

Front

Explain the concept of ecological succession.

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance.
