Question: How does intraspecific competition affect the growth of individuals in a population?1) what would be the manipulated and responding variable?2) using these materials what kind of procedure could you create to test out the question stated aboveMaterials:Seeds(basil, raddish, grass, lettuce)vermiculite or potting soilflower potsscissorsrulerbalance
Intraspecific Competition Intraspecific competition is a particular form of competition in which members of the same species vie for the same resource in an ecosystem (e.g. food, light, nutrients, space). This can be contrasted with interspecific competition, in which different species compete. For example, two trees of the same species growing close together will compete for light, water and nutrients in the soil. Getting less resources, they will perform more poorly than if they grew by themselves (for example lowered growth rates and fewer seed output). Trees have therefore adapted to grow taller or develop larger root systems through natural selection. Grasshoppers provide an animal example. By eating grass, individual grasshoppers deprive their fellow conspecifics of food. This is an example of exploitation competition, which means that the grasshoppers do not interact directly with each other, but have a negative effect on others' growth and reproduction by their effect on a resource (in this case, grass). Here you can plant the seeds and check their growth using a ruler. You can find that they have intraspecific Competition among themselves.
