Science: Ecosystem Passage, Jan. 14, 2022 1. Read the passage about the ecosystems. 2. Answer the questions in complete sentences. 3. Use correct spelling and punctuation marks. Ecosystems Name: An ecosystem is a community of plants and animals and the physical environment in which they live. There are many different types of ecosystems. Some examples include Arctic regions, deserts, evergreen forest, rain forests, mountains, and marshes. Earth has many different types of plants and animals, and they are perfectly adapted to live in one of these communities, or ecosystems. The plants and animals of a particular ecosystem depend on that ecosystem for survival. Animals that live in a rainforest could not live in an Arctic region. Animals living in a marsh could not survive in the mountains. When an ecosystem is changed, the plants and animals living there are affected. Cutting down the trees of a rainforest or evergreen forest would not only change the way an area looks, but it would cause huge changes for the plants and animals living there. Imagine The monkeys of a rainforest living in an area with no trees. They could not do so. Monkeys needed trees for hunting, sleeping, transporting themselves from place to place, and safety. Remove the trees from an ecosystem that is made of trees and the plants and animals living there would perish. Marshlands are an ecosystem that consists of water, trees, and tall grass. Remove any one of those from a marsh and all animals living there would disappear. Drain the water from a marsh and the animals and the plants would disappear. With no water, the plants of a marsh would die. With no water, the animals that live in water would die. Animals that hunt for food in and around the water would disappear. Where would they go? Animals used to living and hunting in a wet area would either die or go in search of another wet area in which to live. A marsh could be changed in another way: pollution. Polluting the water of a marsh would cause similar results. Science Standard: S4L1.
