Where does the energy in almost all food come from?
Energy in almost all food can be traced back to the sun. Plants use light energy to produce their food through photosynthesis. Plants are then eaten by animals. Those animals are then eaten by other animals.
A living thing that is no longer found alive anywhere on Earth today.
Extinction
A sequence of living things in which each one feeds on the living thing below it.
Food Chain
What was the name of the t-rex fossil Doug visited as a kid?
Sue
True or False?
Zebras are apex predators.
False
True or False?
Scientists have reason to think that NOT ALL of the dinosaurs died in the Cretaceous extinction. Explain your answer.
True, birds are still living today.
A food web is a model made of intersecting food chains.
Food Web
Why are producers called producers? How did they get their name?
Plants are producers because they produce their own food through photosynthesis.
What is the role of worms, bacteria, and fungi in a food web?
These living things are decomposers. They recycle matter, by breaking down dead and decaying matter. They turn it into nutrients in the soil, which plants use. If ecosystems didn’t have decomposers, dead plants and animals would just pile up.
Which correctly shows the flow of energy through a food we
a. producers → decomposers → consume
b. producers → consumers → decompose
c. decomposers → consumers → producers
b. producers → consumers → decompose
A living thing (almost always a plant) that takes energy from the sun and make its own food. They are found in the first level of a food web.
Producer
Why are consumers called consumers? How did they get their name?
Animals are consumers because they consume plants or other animals.
Why are apex predators so important to the food web?
Apex predators help control the balance of an ecosystem by keeping the populations of other animals in check.
Choose the statement that most accurately describes why the dinosaurs die
a. The dinosaurs died from earthquakes set off by the asteroid impac
b. The dinosaurs burned up instantly from a giant fireball caused by the asteroi
c. Most dinosaurs starved due to the collapse of their food web
d. Most dinosaurs suffocated because they couldn’t breathe air full of asteroid dus
e. The dinosaurs froze to death when the sun was blocked out.
c. Most dinosaurs starved due to the collapse of their food web
Living things that break down dead and decaying organisms. The most common decomposers are bacteria and fungi.
Decomposer
An animal found at the top of a food web and is not eaten by any other animals. Examples include sharks, owls and lions.
Apex Predator
Why do animals eat other animals?
Animals eat other animals to obtain energy and building blocks (nutrients) in order to grow and repair.
Name one organism you think was most likely to survive the Cretaceous extinction?
Omnivores, small animals, decomposers, or plants.
A process by which plants use sunlight to make sugar from carbon dioxide and water.
Photosynthesis
Usually made by gathering plant material such as leaves and vegetable peels into a pile and letting it decompose over many months thanks to bacteria and fungi. The resulting substance can be used as a fertilizer for plants.
Compost
