Assignment about living things and their environment

Assignment

After reading the section on living things and the Environment in your textbook, apply your knowledge to answer the following questions in a new blog post on your blog. What needs are met by an organism's environment? What are the two parts of an organism's habitat with which it interacts? What are the levels of organization within an ecosystem? Why do you find different kinds of organisms in different habitats? Think about what will soon start happening within Belgrade. How do animals prepare for such a change?



Now, search for and embed a video showing a living thing in its environment. What would happen if we took away one or more of the living or nonliving factors in its environment? Which factors could they survive without?

Answers

1. There are a lot of needs met by an organism's environment. Firstly, the only environment that can meet those needs is the organism's natural habitat. It provides it with food. In it's natural habitat, the organism can find food, whether it's meat, plants or other microscopic beings. It can also find home. Some beings live in the trees, others in the bushes, the sea, etc. The habitat also provides the organism with oxygen and enough sun.

2. The organism interacts with other living organisms, as well as the physical environment. A biosphere is a place on Earth where organisms live. The biospheres consist of geographical areas, which are usually called biomes. A biome is a collection of a bunch of different ecosystems. Ecosystems include grasslands, rain forests, the ocean, etc., as well as different organisms, such as bacteria, amphibians, mammals, and many more.

3. Species; which is a population of the same kind of organisms, which are able to breed together.
Community; A group of different populations living in the same ecosystem, and somehoe interacting with each other.
Ecosystem; It is an area where climate, animals, plants and landscape continously interact with each other.
Biosphere; The largest unit of living systems.

4. Because not all organisms are capable of adapting to more then one environment. Let's take a salamander, for example. The salamnder is adapted to living in a dark, moist environment, and it would probably die in a desert, because it would get dehydrated.

5. Winter will come soon to Belgrade. Some animals prepare differently then others. Squirells, for example, are gathering nuts and grains to feed themselves through the entire winter season. Some birds are off, flying to warmer places, until winter is over. Bears (in the zoo, or bigger forests), are eating a lot more then usual, so that they have a thick layer of fat, to feed themselves of, during the long winter.
