If the number of individuals in a predator population dropped to zero, what would happen to the size of their prey population What is increase? DAILY DOUBLE All the living things in an area make up the What is community? To determine the size of a population that is hard to find it may be easier to observe the tracks and other signs that are left behind, this method is called What is indirect observation? An interaction in which one organism kills and eats another is called What is predation? A relationship in which both species will benefit is called What is mutualism? A relationship where one organism benefits at the expense of another is called What is parasitism? A relationship in which one organism benefits and the other is neither helped nor harmed is called What is commensalism? A long term relationship between two species that benefits at least one of the species is called What is symbiosis? Organisms live in different habitats because they require different _____. What are needs? Three basic needs What are water, food, and shelter? An environmental factor that prevents a population from growing is called What is a limiting factor? An organisms needs are found in its ? What is a habitat? A new housing development causes this need to become a limiting factor What is space? If a mouse eats seeds and is eaten by a snake, what role does the snake play in the food chain? What is a second level consumer? An organisms particular role, or how it makes its living is called What is a niche? The struggle between organisms to survive in a habitat with limited resources is known as What is competition? A parasite lives on or in a What is a host? The study of how living things interact with each other and with their environment is known as What is ecology? FINAL JEOPARDY FOOD WEBS ?
