Discuss the concept of carrying capacity in relation to resource availability.

• Carrying capacity is the average number of individuals of a species that an environment can sustainably support given the available resources.

• Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support given the available resources.

• Carrying capacity is the maximum number of individuals of a species that an environment can support regardless of the available resources.

• Carrying capacity is the minimum number of individuals of a species that an environment can sustainably support given the available resources.

How do population dynamics impact biodiversity?

• Population dynamics have no impact on biodiversity.

• Biodiversity is solely determined by external factors and not influenced by population dynamics.

• Population dynamics only impact the size of individual species, not overall biodiversity.

• Population dynamics impact biodiversity by influencing the abundance and distribution of species within an ecosystem.

What is population growth?

• Decrease in the number of individuals in a population over time.

• The average number of individuals in a population.

• The movement of individuals from one population to another.

• Increase in the number of individuals in a population over time.

What is the evidence that solar radiation is less important to global warming than the increase in greenhouse gases?

• temperatures have increased more in the summer than in winter

• temperatures have increased more in the winter than in summer

• temperature increases have been uneven across the globe

• there is a historic correlation of CO₂ and temperature

• There is a lack of temperature change in some areas

Particulate matter can increase global warming by

• reacting with chlorofluorocarbons

• reducing surface absorption of ultraviolet radiation

• producing additional nitrous oxides

• reflecting radiation

• lowering surface albedo

What are population dynamics?

• The study of how individuals within a population interact with each other.

• The study of how populations of organisms remain constant over time.

• The study of how populations of organisms change due to external factors.

• The study of how populations of organisms change over time.

Define carrying capacity.

• Maximum population size of a species that the environment can sustain indefinitely

• The total area of land available for a species to inhabit

• The average number of offspring produced by a species

• The number of individuals in a population that exceeds the environment's resources

What are the components of an ecosystem?

• The components of an ecosystem include biotic (living) and abiotic (non-living) factors such as plants, animals, microorganisms, soil, water, air, and sunlight.

• The components of an ecosystem include only water and air

• The components of an ecosystem include only animals and plants

• The components of an ecosystem include only sunlight and soil

Why is biodiversity important for ecosystems?

• Ecosystems are better off with less biodiversity

• Biodiversity has no impact on ecosystems

• Biodiversity only causes instability in ecosystems

• Biodiversity helps maintain the balance of ecosystems and provides resilience to environmental changes.
