What is the function of lysosomes in a cell?

Back

Lysosomes are organelles that contain digestive enzymes to break down waste materials and cellular debris, often referred to as the 'trash collectors' of the cell.

Front

What type of organisms are classified as primary consumers?

Back

Primary consumers are typically herbivores that eat plants.

Front

What is the optimal pH for enzyme A to function effectively?

Back

The optimal pH for enzyme A is 2.

Front

What factors can lead to an increase in a population?

Back

Factors that can cause a population to increase include an increase in food supply, removal of predators, and removal of disease.

Front

How does covering a field of grass with a parking lot affect its productivity?

Back

Covering a field of grass with a parking lot makes the ecosystem less productive because there will be less grass available to make glucose.

Front

Define primary consumers in an ecosystem.

Back

Primary consumers are organisms that eat producers (plants) and are typically herbivores.

Front

What role do mitochondria play in a cell?

Back

Mitochondria are known as the powerhouse of the cell, responsible for producing energy (ATP) through cellular respiration.

Front

Explain the concept of an ecosystem's productivity.

Back

Ecosystem productivity refers to the rate at which energy is produced and made available to support the food web, often measured in terms of biomass.

Front

What is the significance of pH in enzyme activity?

Back

The pH level can significantly affect enzyme activity, as each enzyme has an optimal pH range where it functions best.

Front

What is the impact of removing predators from an ecosystem?

Back

Removing predators can lead to an increase in the population of prey species, potentially causing overpopulation and resource depletion.
