What are producers and consumers in an ecosystem?

Producers are organisms that create their own food through photosynthesis (e.g., plants), while consumers are organisms that depend on others for food (e.g., animals).

What is a food chain?

A food chain is a linear sequence of organisms where nutrients and energy pass through from one organism to another, starting with producers and moving up to various levels of consumers.

What is a food web?

A food web is a complex network of feeding relationships among organisms in an ecosystem, showcasing how different food chains intersect.

What is an energy pyramid?

An energy pyramid illustrates the amount of energy available at each trophic level of a food chain, typically decreasing as one moves up the pyramid.

What is the 10% Rule in ecology?

The 10% Rule states that, on average, only 10% of the energy from organic matter is transferred to the next trophic level; the rest is lost primarily as heat.

What is overexploitation?

Overexploitation refers to the harvesting of resources at rates faster than they can replenish, often leading to population declines or extinction of species.

What is global warming?

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, primarily greenhouse gas emissions.

What are greenhouse gases?

Greenhouse gases are gases that trap heat in the atmosphere, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

What is the greenhouse effect?

The greenhouse effect is the process by which greenhouse gases trap heat in the atmosphere, warming the Earth and affecting climate patterns.

What is acid rain?

Acid rain is precipitation that contains elevated levels of sulfuric and nitric acids, often due to industrial pollution, leading to forest damage and lake acidification.

What is lake acidification?

Lake acidification occurs when lakes become more acidic due to acid rain, impacting aquatic ecosystems and species.

What are the hydrosphere, geosphere, biosphere, and atmosphere?

The hydrosphere includes all water bodies; the geosphere is the Earth's solid structure; the biosphere encompasses all living organisms; and the atmosphere is the layer of gases surrounding the planet.

What are the carbon, phosphorus, and nitrogen cycles?

These cycles describe the movement of carbon, phosphorus, and nitrogen through the environment, involving biological, geological, and chemical processes.

What is eutrophication?

Eutrophication is the process by which excess nutrients, particularly nitrogen and phosphorus, lead to excessive growth of algae in water bodies, causing oxygen depletion.

What is biodiversity?

Biodiversity refers to the variety of life in a particular ecosystem, encompassing species diversity, genetic diversity, and ecosystem diversity.

What is habitat destruction?

Habitat destruction is the process by which natural habitats are altered or destroyed, often due to human activities, leading to loss of biodiversity.

What is poaching?

Poaching is the illegal hunting, capturing, or killing of wildlife, often for profit or to supply black markets.

What is extinction?

Extinction refers to the permanent loss of a species from the planet.

What is de-extinction?

De-extinction is the process of using biotechnological methods to bring back species that have been extinct.

What is biotechnology?

Biotechnology is the use of living systems and organisms to develop or create products, commonly used in genetic engineering and medicine.

What is coral bleaching?

Coral bleaching is the process by which corals lose their symbiotic algae (zooxanthellae) due to stressors like temperature increases, leading to a loss of color and vitality.

What are marine algae and Kelp Forests?

Marine algae, including kelp, are large seaweeds found in underwater forests that support diverse marine life and provide ecosystem services.

What is erosion?

Erosion is the process by which soil and rock are removed from one location and transported to another, often leading to landscape changes.

What is recycling?

Recycling is the process of collecting and processing materials that would otherwise be discarded and turning them into new products.

What are renewable and non-renewable resources?

Renewable resources are natural resources that can replenish over time (e.g., solar energy), while non-renewable resources are finite and cannot be replaced (e.g., fossil fuels).

What is deforestation?

Deforestation is the large-scale removal of forest cover, often for agricultural or urban development, leading to biodiversity loss and carbon emissions.

What is reforestation?

Reforestation is the process of planting trees in an area where forest cover has been reduced or destroyed.

What is primary ecological succession?

Primary ecological succession occurs in lifeless areas where soil has not yet formed (e.g., after a volcanic eruption), leading to the establishment of an ecosystem.

What is secondary ecological succession?

Secondary ecological succession occurs in areas where a disturbance has destroyed a community but left the soil intact (e.g., after a forest fire).

What are biotic and abiotic factors?

Biotic factors are living components of an ecosystem (e.g., plants, animals), while abiotic factors are non-living elements (e.g., temperature, water, soil).

What is carrying capacity?

Carrying capacity is the maximum population size of a species that an environment can sustainably support.
