Exploring Ecology Concepts in EOC Biology

What does the study of ecology primarily focus on?

• The examination of chemical processes in the atmosphere.

• The study of human behavior in natural settings.

• The relationships between living organisms and their physical environment.

• The analysis of geological formations.

What are abiotic factors in an ecosystem?

• Non-living elements like water and sunlight.

• Living organisms such as plants and animals.

• Diseases affecting plant life.

• Decomposed organic matter.

What does the term 'biodiversity' refer to?

• The number of keystone species in an ecosystem.

• The variety of living species in a particular area.

• The uniformity of species in a given area.

• The variety of non-living components in an ecosystem.

What role do keystone species play in an ecosystem?

• They are the most abundant species in the ecosystem.

• They primarily act as primary consumers.

• They have no significant impact on the ecosystem's structure.

• They help maintain the ecosystem's stability.

What is the primary source of energy in most ecosystems?

• Wind

• The Sun

• Water currents

• Geothermal heat

What is a food web?

• A complex network of feeding relationships among organisms in an ecosystem.

• A single pathway of feeding relationships among organisms in an ecosystem that results in energy transfer.

• A graphical representation of water flow in an ecosystem.

• A system used to categorize organisms based on their genetic similarities.

What is mutualism?

• A relationship where one species benefits and the other is harmed.

• A relationship where both species benefit.

• A relationship where one species benefits and the other is unaffected.

• A relationship where both species are harmed.

What are renewable resources?

• Artificial resources created by humans.

• Natural resources such as oil and coal.

• Resources that can regenerate quickly and that are replaceable.

• Resources that once depleted cannot be used again.

What is the significance of the nitrogen cycle?

• It describes the movement of nitrogen within the atmosphere only.

• It primarily focuses on the production of nitrogen-based fuels.

• It involves the conversion of nitrogen into usable forms for plants and animals.

• It is a process exclusive to aquatic ecosystems.

What is ecological succession?

• The process by which ecosystems are destroyed by natural disasters.

• A theory that describes the evolution of the earth's geological features.

• The rapid increase in an ecosystem's biodiversity.

• The gradual process of change and replacement of the types of species in an ecosystem.
