Finals For Environmental Science

Humans increase carbon dioxide (CO2) in the atmosphere by (select all that apply):

cutting down trees, combustion driving cars, and burning fossil fuels in industrial plants

What's the formula for Photosynthesis?

6CO2 + 6H2O --light--> C6H12O6 + 6O2

Explain how human activities disrupt the carbon cycle and suggest potential mitigation strategies to minimize these impacts

Human activities enumerate the amount of carbon present, disrupting the carbon cycle further with a dilemma of an excessive amount of carbon that affects ecosystems and causes global warming, where the earth is growing warmer due to the toxins/pollutants in the atmosphere over accumulating. Some suggestions are to plant more trees, use non-renewable alternatives, and to have use energy-efficient transportation methods to reduce the amount of carbon present.

What is a cycle that involves the transformation/movement of water

hydrologic cycle

What's a cycle that involves the transformation/movement of nitrogen

nitrogen cycle

What's a cycle that involves the transformation/movement of carbon

carbon cycle

Which of the following is NOT a characteristic of all living things?

Can move over time

In order from smallest to largest, the ecological levels of organization are:

individual, populations, community, ecosystem, biome

Recall that carrying capacity is affected by limiting factors. LIST 1 potential limiting factors that scientists could investigate to understand the carrying capacity of African wild dogs.

A potential limiting factor that scientists could investigate to understand the carrying capacity of African wild dogs is that the reproductivity rate is not as favorable as to keep their population stable because each year the female African wild dogs only give birth to one litter every year. With this in mind, the low reproductive amount of litter from the female African wild dog could affect the carrying capacity to be lower. Moreover, habitat loss and human activities would pose as a potential limiting factor that minimizes the maximum amount of African wild dogs that can live in their specific region/habitat.

The cape buffalo eats during the wet season diet is mainly:

Themada triandra

What is the difference in the cape buffalo's diet in the wet season and dry season?

The difference in the cape buffalo's diet in the wet season and dry season is that there is a higher percentage that the cape buffalo eats during the wet season due to a potential factor that there is a higher abundance of the specific plant species, while during the dry season there is a less percentage possibly because the plant species isn't as abundant and due to a possibility that the animal could have a preference for certain plant species during the dry or wet seasons.

Why during the wet season, the competition between zebras, gazelles, wildebeests and cape buffalo is lessen?

During the wet season, the competition between zebras, gazelles, wildebeests and cape buffalo is lessened because there is a higher abundance of the various plant species, specifically because when there is more water available for the plant to use, the plants would be able to grow more efficiently, while during the dry season there is a lack of rain for more plants to grow in which causes competition because there is less plants available as a food source.

Plant cells use photosynthesis to make food. Plant cells also use cellular respiration to get energy from the food they make. How is cellular respiration different from photosynthesis?

Photosynthesis produces oxygen, and cellular respiration produces carbon dioxide and Photosynthesis requires water, and cellular respiration produces water

What is environmental science?

The study of how the natural world works, how the environment affects us, and how we affect it

Goods and services
