Part of & Resources in Ecosystems

What might happen to the ecosystem if the hunting season was canceled (set to zero days)?

• The producers would overpopulate

• The hunted animal would overpopulate and increase competition

• There would be less competition for food

• The ecosystem would remain balanced

This graph shows how the amount of meat the world eats has changed over time. How could this affect the supply of food AND Earth's natural resources?

• The supply of food will decrease. The amount of resources will increase.

• The supply of food will increase. The amount of resources will decrease.

• Both the supply of food and Earth's natural resources will increase.

• Both the supply of food and Earth's natural resources will decrease.

This graph shows how the amount of meat the world eats has changed over time. Describe the trend that this graph shows.

• The supply of food is increasing

• Humans are eating more meat than ever before, so the supply of food will decrease.

• Humans are eating the same amount of meat as always, so the supply of food is going to increase

• The most popular type of meat is poultry, but the amount of chickens cannot support the human population in many countries.

• The population has steadily increased over time

• The population increased and then decreased

• The population decreased and then increased

If the population of the United States increases, how might this affect the Earth's natural resources?

• We won't need as much food so there will be more natural resources

• We will need to use more natural resources to raise more animals for a larger food supply

• We will need to use more natural resources since we will not need as many animals

• The animals will overpopulate since no one will be eating them. This will cause a decrease in the amount of Earth's natural resources.

What happens when the population of prey decreases?

• The population of predator will increase

• The population of predator will increase and then decrease

• The population of predator will not be affected

• The population of predator will decrease shortly after

How are the populations of predators and prey related?

• If there is not enough prey, the predators will die out

• If there is too much prey, the predators will die out

• If there are not any predators, the prey will die out

• If there are too many predators, the prey will overpopulate

How are ecosystems disrupted?

• Due to the care and excessive maintenances of natural spaces.

• As a result of creating new natural resources.

• Due to the occupation, pollution and destruction of natural spaces.

What is the correct definition of a population.

• Groups of individuals of the same species.

• Made up of the different populations living together.

• All the organisms living in a habitat AND the non-living parts of the habitats e.g. an ocean.

• Trying to get enough resources.
