An organism that needs to eat other organisms to obtain energy is known as a:: Consumer. The position that an organism occupies within a food chain is called its..: Trophic Level. an organism that gets energy from eating other things: consumer. an organism that eats only plants: herbivore. an organism that eats only meat: carnivore. an organism that eats both plants and animals: omnivore. shows how energy is passed from one organism to the next: energy pyramid. An organism that eats the secondary consumer: Tertiary Consumer. Total amount of living tissue within a given trophic level. : Biomass. If a plant lacked carbon dioxide but had plentiful water and sunlight, the carbon dioxide would be considered a ______________: Limiting Factor. Network of feeding interactions through which both energy and matter move, may contain multiple food chains. : Food Web. Each individual level of a food chain or food web. : Trophic Level . Simple and Direct series of organisms in which energy is transferred from one organism to the next: Food Chain. a living organism, such as a plant, that makes its own food, using the energy of the Sun, water and carbon dioxide: producer. an animal that eats dead organisms: scavenger . Biotic can be defined as: the living parts of an environment. Abiotic can be defined as: . Process in which nitrogen can be fixed by lightning, bacteria, or industries: Nitrogen Fixation. Process by which bacteria convert nitrogen compounds in the soil back into atmospheric nitrogen: Denitrification. Matter can't be created nor destroyed; it can transformed from one type to another. : law of conservation of matter

All food webs and food chains begin with _________________: producers. In this energy pyramid, which organisms have the most energy available: Producers. How many carnivores are shown in this food web: 5. In an ecological pyramid, which type of organism always has the least amount of energy available: Apex Predator. If there are 100 Kcal of energy available in the producers, how much energy would be available in the primary consumers: 10 Kcal. In this ecological pyramid which type of consumer gets only 10% of the energy stored in plants: Herbivore. Which organism is the carnivore: . Which organism is the omnivore: . What percentage of energy is passed on to each tropic level: 10%. Which organism do the owl and the weasel compete for in the food web: Shrew. Based on the image, which organism recieves the least amount of energy from the producer: Owl. In a food web, arrows point at:: who gets energy.. An organism that eats the secondary consumer: Tertiary Consumer. Organisms which carry out the process of decomposition by breaking down dead or decaying organisms: Decomposer. A connection of food chains with many food energy paths in an ecosystem is a ____________: food web. Who does the grasshopper get energy from? : Grass. What is this called: Food Chain. Where does the energy start in this food chain: Sun. How are primary consumers different from secondary consumers: Primary consumers eat only plants; secondary consumers eat other consumers.

Which organism in this food chain is a tertiary consumer? Hawk. In this food pyramid, which level has the greatest amount of energy? Producers. How much energy is passed from one trophic level to the next? 10%. What happens to the energy that is not passed on to the next level? A and B both. decomposer. Based on what is depicted in this food chain, which organism might possibly be an herbivore? Insect. each level of the food chain is called a ________ level. Trophic. A series of interrelated food chains in a given ecosystem is called a ______________. food web
