What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, often following a disturbance, leading to a more stable community.

What is a control group in an experiment?

Back

A control group is a standard of comparison in an experiment that is not exposed to the treatment or condition being tested, allowing for a baseline to measure the effects of the treatment.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O), which are converted into glucose and oxygen using sunlight.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What does it mean for water to be a universal solvent?

Back

Water is called a universal solvent because it can dissolve a wide variety of substances, making it essential for many biological processes.

Front

What is cohesion in terms of water properties?

Back

Cohesion is the property of water that allows molecules to stick to each other, resulting in surface tension.

Front

What is adhesion in terms of water properties?

Back

Adhesion is the property of water that allows it to stick to other substances, which is important for processes like capillary action.

Front

What is surface tension?

Back

Surface tension is the elastic-like force existing on the surface of a liquid, caused by the cohesive forces between liquid molecules.

What is the significance of the apex predator in an ecosystem?

Back

The apex predator is at the top of the food chain and helps regulate the populations of other species, maintaining the balance of the ecosystem.
