Give an example of mutualism.

• The relationship between colobus monkeys and fig trees, where monkeys eat the figs and help disperse the seeds.

• The relationship between a lion and a zebra, where the lion hunts the zebra for food.

• The relationship between a bee and a flower, where the bee collects nectar and pollinates the flower.

• The relationship between a shark and a remora fish, where the remora cleans the shark's teeth.

What is exponential growth in a population?

• Exponential growth occurs when a population increases rapidly due to abundant resources, leading to a J-shaped growth curve.

• Exponential growth is a slow increase in population size due to limited resources.

• Exponential growth refers to a steady decline in population over time.

• Exponential growth happens when a population remains constant despite resource availability.

What is photosynthesis?

• The process by which plants absorb water from the soil.

• 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, and releasing oxygen as a byproduct.

• The method by which animals convert food into energy.

• The way in which plants grow towards sunlight.

What is the difference between immigration and emigration?

• Immigration is the movement of individuals into a population, while emigration is the movement of individuals out of a population.

• Immigration is the movement of individuals out of a population, while emigration is the movement of individuals into a population.

• Immigration refers to the legal process of obtaining citizenship, while emigration refers to the illegal movement of people across borders.

• Immigration and emigration are terms that refer to the same process of moving between countries.

What is a food web?

• A simple chain of organisms that eat one another.

• A complex network of interconnected food chains in an ecosystem, showing how different organisms are related through feeding relationships.

• A diagram that shows the energy flow in a single species.

• A list of all the plants and animals in a specific area.

In which type of cell would you observe a cell plate during mitosis?

• Animal cells

• Fungal cells

• Plant cells, such as onion root cells

• Bacterial cells

What is a food chain?

• A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

• A food chain is a circular pattern of energy flow in an ecosystem.

• A food chain is a list of all the organisms in a habitat.

• A food chain is a method of food preservation used in cooking.

What is logistic growth in a population?

• Logistic growth occurs when a population grows exponentially without limits.

• Logistic growth occurs when a population's growth slows as it approaches the carrying capacity of its environment, resulting in an S-shaped growth curve.

• Logistic growth is characterized by a constant rate of growth regardless of population size.

• Logistic growth happens when a population decreases due to limited resources.
