Environmental Science Quiz on Biodiversity and Habitats

Clearing trees, often on a large scale, for other uses.

The damaging or removal of a natural environment, which harms the species that live there.

The variety of life in a particular ecosystem or region.

The increase in the number of humans on Earth.

Contamination of the oceans by harmful substances from human activities.

The process of obtaining resources from the earth (like minerals or wood).

A process where excess nutrients in water lead to a decrease in oxygen levels, harming aquatic life.

Methods to manage resources without depleting them and without harming the environment.

A diverse group of eukaryotic organisms that are not plants, animals or fungi. They can be unicellular or multicellular, and some may have cell walls, chloroplasts and photosynthesize.

Single-celled organisms, like bacteria and blue-green algae, that lack a nucleus and other membrane-bound organelles.

A green pigment found in plants and some protoctists that absorbs light energy for photosynthesis.

A type of plant that reproduces by spores and has leaves called fronds.

Plants that reproduce sexually through flowers and produce seeds.

A type of flowering plant with single seed leaves, flower petals in multiples of 3, and parallel leaf veins.

A type of flowering plant with two seed leaves, flower petals in multiples of 4 or 5, and reticulated leaf veins.

Non-living entities that require a host cell to replicate, containing genetic material (RNA or DNA) inside a protein coat.

Organisms that obtain energy from consuming both plants and animals.

The movement of energy from one organism to another in a food chain, with energy lost at each transfer.

The clearing of trees, often on a large scale, for other uses like agriculture or building.

It destroys habitats for animals, causes soil erosion, and contributes to climate change.

Planting new trees to replace those cut down, ensuring the forest can regenerate.

Pollutes water sources, harming aquatic life and ecosystems.

Flows into waterways, causing excessive algae growth (eutrophication) that harms aquatic life.

Excess nutrients cause algae overgrowth, blocking sunlight and consuming oxygen, leading to fish death.

They don't break down easily, harm animals, and release toxins into the soil and water.

Rain with high acidity caused by sulfur dioxide released from burning fossil fuels.

A resource that can be used without depleting it, so it's available for future generations.

Resources that cannot be replaced once used, like fossil fuels.

Development that meets today's needs without compromising future generations' abilities to meet their own needs.

Meeting human needs for resources while protecting the environment and ensuring sustainability.

Managing forests for timber and paper production while ensuring their regeneration for future use.

Managing fish populations to ensure their long-term survival and availability.

Species at risk of becoming extinct due to factors like habitat loss, pollution, or hunting.
