Humans change ecosystems by burning fossil fuels, cutting down trees in the rain forest, driving gasoline-powered vehicles and doing other things that affect the climate of a particular environment. In all ecosystems, living things interact with each other in their physical environments. Factors such as sunlight, precipitation, moisture and temperature also affect these interactions.Know More
Driving gasoline-powered vehicles and burning fossil fuels are among several activities that produce greenhouse gases. These gases affect the amount of heat in the Earth's atmosphere. They also affect the reflectivity of the Earth's surface and the amount of sunlight that reaches Earth. All of these things contribute to global warming, which affects ecosystems in many ways.
In some ecosystems, temperature affects the mating and migration habits of some species. According to the Environmental Protection Agency, 28 migratory bird species are nesting earlier on the East Coast due to climate changes. Some butterfly species have also changed their migration habits due to the warming. Cutting down trees affects the rain forest ecosystem in several ways. With fewer trees to provide cover, more of the sun's energy reaches the rain forest floor. Too much sunlight causes the soil to dry out, making it difficult for plants to thrive. If plants die off, there is less food available to the herbivores in the ecosystem. Deforestation also reduces the amount of water vapor returned to the environment, affecting moisture levels in the rain forest.Learn more about Earth Science
Ocean ecosystems or marine ecosystems are made up of a community of living and nonliving things found in a localized area in any ocean. In an ecosystem, the plant life and animal life support one another and are each dependent on the other for the success of the ecosystem.Full Answer >
The sun is important to Earth because it helps regulate the climate, is the main source of energy for producers in the ecosystems and it keeps the oceans from freezing, along with providing light. If just one of these factors changed dramatically, it would impact all life on Earth. Without the sun, the planet's oceans would freeze, temperatures would drop and all life would die off without light or food.Full Answer >
A climate graph is a type of chart that uses both line and bar graphs to compare temperature and precipitation in a given geographic region over a specific period of time. In all climate graphs, the date range is represented by numbers at the bottom of the chart. The dates can include any period of time, though longer spans, such as months or years, are the most common.Full Answer >
The five types of climates are tropical, dry, moderate or temperate, continental and polar. Climate is commonly classified using the Köppen Climate Classification Scheme, which divides climates into five distinct groups that include the letters A, B, C, D and E. This system classifies several types of climates and subtypes.Full Answer >
