Ask students to think about the benefits of studying animal behavior and ecological interactions without interference by human observers. An organism that must obtain their nutrients by eating (consuming) other organisms is called a consumer, or a heterotroph. Two different types of competition are intraspecific and interspecific competition. chains begin from producers to consumers and the major feeding levels are Relationships An Ecological relationship is the relationship between organisms in an ecosystem. Relationships among Organisms evidence interactions symbiotic environment W K Words to Know 2 Fill in this table as you work through the lesson. An ecological community is defined as a group of actually or potentially interacting species living in the same place. A community is bound together by the network of influences that species have on one another. The patterns of interactions of organisms with their environment, both its living and nonliving components, are shared. There are 3 types of interactions in an ecosystem that fall under the interaction of symbiosis: Mutualism Commensalism Parasitism These types of interactions occur when two species are in. plants that carry on photosynthesis. Ask: Other than the shark, are there any other organisms you see? Some organisms can make their own food, and other organisms have to get their food by eating other organisms. Ecosystems and habitats have different relationships interactions occurring within them.
