Exam Review (Units 0-4)

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. In aquatic ecosystems, water has a high specific heat capacity, meaning it absorbs and releases heat slowly.

Front

Describe the flow of energy in an ecosystem.

Back

The flow of energy in an ecosystem typically follows a path from producers (like plants) to primary consumers (herbivores) to secondary consumers (carnivores). This flow can be represented as ABD, where A is producers, B is primary consumers, and D is secondary consumers.

Front

What is decomposition in the Carbon Cycle?

Back

Decomposition is the process where organic matter is broken down by microorganisms, releasing carbon dioxide back into the atmosphere. It is a crucial part of the Carbon Cycle.

Front

Define population in ecological terms.

Back

A population is a group of individuals of the same species that live in a specific area and interact with one another. For example, a group of penguins in a particular region represents a population.

Front

List the levels of ecological organization from largest to smallest.

Back

The correct order of ecological organization from largest to smallest is: biosphere, biome, ecosystem, community, population, organism.

Front

What role do producers play in an ecosystem?

Back

Producers, such as plants and algae, convert sunlight into chemical energy through photosynthesis, forming the base of the food chain.

Front

Explain the process of photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water. It is essential for the survival of most organisms.

Front

Define biome.

Back

A biome is a large geographical biotic unit, a major community of plants and animals with similar life forms and environmental conditions, such as a desert or rainforest.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.
