The sequence of who eats whom in a biological community. A food chain shows how animals are connected in their search for food within an ecosystem. A _____________shows how each living organism gets its food.
Examples: Non-examples: Human Frog Cat Ladybug Food Web Sitting down to eat dinner A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals. One path of energy.
An Autotroph is an organism that makes its food from light or chemical energy without eating it; also called primary producers. An ______________ is a living thing that makes its own food from sunlight, air, and soil. Green plants are producers who make food in their leaves. auto- “self”; -troph “an organism with nutritional requirements”
Autotroph Examples: plants on land algae in water bacteria Non-examples: animals fungi
hetero- “different”; “other” -troph “an organism with nutritional requirements” An organism that gets its energy by eating other organisms. All animals are called consumers; they need to consume (eat) plants and/or animals; they are also known as _______________. Heterotrophs are unable to make their own food; they are the consumer in the food chain. They must take food from other sources to survive.
Heterotroph Examples: Herbivore: a green sea turtle eats sea grasses and algae Carnivore: a tiger eats a monkey Omnivore: a human eats steak and vegetables Non-examples: Plants that use photosynthesis such as: algae and phytoplankton Venus-fly trap bacteria
An organism that eats plants. herb- plant -vore: eater
__________ A deer eats grass and plants found in its habitat. Since the deer eats only plants, it is a __________. Non examples: Meat eaters such as: tigers, sharks, bears, and hawks. Autotrophs-make their own food; plants, algae, and bacteria. Herbivores are animals which only eat plant material. This means leaves, flowers, fruits or even wood. Sheep, horses, rabbits and snails are well known examples of herbivores which eat grass and leaves.
An organism that eats meat. carn-flesh or meat -vore: eater
A leopard seal eats fish and penguins. It never eats plants. Since the leopard seal eats only meat, it is a _______________. Examples: Carnivores generally eat herbivores and other carnivores. Bobcats, wolves, hawks, snakes, frogs and spiders. Non-examples: Veggie eaters such as: rabbits, hamsters, mice and deer. They only eat leaves, flowers, fruits, and wood and do not eat any other animals. Autotrophs—make their own food; plants, algae, and bacteria.
An organism that eats both plants and meat. omni- all or everything -vore: eater
______________. A raccoon eats other animals like crayfish, as well as plant life. Since the raccoon eats both plants and animals it is an ______________. Examples: Omnivores eat both plants and meat. Chickens are omnivores. They eat seeds, but they can also eat worms. Human beings are also omnivores, although some people choose not to eat meat. These people are called vegetarians. Non-examples: Herbivore: (plant eater) mice, hamster, and horse Carnivore: (meat eater) coyote, owl, and frog Autotroph: (makes it’s own food) plants, algae, and bacteria
A meat-eater that eats autotrophs. An example of a ________________ is a rabbit that eats grass.
A meat-eater that eats primary consumers An example of a _____________________ is a snake that eats rabbits.
A meat-eater that eats secondary consumers. An example of a _______________ is an owl that eats snakes.
A meat-eater that eats tertiary consumers An example of a _______________ is a wolf that eats an owl.
An organism that breaks down dead organisms. A _________________ is a living thing that gets energy by breaking down dead plants and animals. Fungi and bacteria are the most common decomposers.
Examples: Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Scavengers are animals that find dead animals or plants and eat them. While they eat them, they break them into small bits. Flies, wasps and cockroaches are scavengers. Earthworms are also scavengers, but they only break down plants. Non-examples: Herbivore: (plant eater) rabbit, deer, and cow Carnivore: (meat eater) human, seal, and alligator Omnivore: (both plants and meat eater) bear, raccoon, and monkey Autotroph: (makes it’s own food) plants, algae, and bacteria
