Energy, Producers, and Consumers
Transcript of Energy, Producers, and Consumers
b. Propose a question that a scientist might ask about the variety of organisms found in deep-sea vents?
3 . : Energy, Producers, and Consumers
What are primary producers?
-organisms that jump-start the food chain by creating energy for other organisms
How do consumers obtain energy and nutrients?
-get energy and nutrients from organisms they eat
An organism that can use sunlight and chemicals as energy to make their own food
The first producer of energy-rich compounds that are later used by other organisms
A process that plants use to make their own food
A process in which chemical energy is used to produce carbohydrates
An organism that obtains food by consuming other living things; also called a consumer
An organism that relies on other living things for energy
An organism that only eats meat
An organism that only eats plants
An organism that only eats dead organisms.
An organism that eats both plants and animals
An organism that breaks down and obtains energy from other organisms
An organism that feeds on plants and animal remains and other dead matter
2 a. Explain how consumers obtain energy?
b. How are detritivores different from decomposers? Provide an example of each.
Detritivores vs. Decomposers
-eats plants and animals that are dead
breaks down dead matter for energy
-plants and animals get energy from sunlight
-energy is converted for other living organisms
-algae, bacteria, and plants
-autotrophs use chemical energy for food
-first producers of energy
Energy From the Sun
-photosynthesis uses light energy
-carbon dioxide and water convert to oxygen
-no photosynthesis=no oxygen to breathe!!
-algae use photosynthesis in water ecosystems
Life Without Light
-primary producers use chemical energy
-process called chemosynthesis
-chemical energy used to produce carbohydrates
-found in dark, deep areas with no light
-heterotrophs get energy from other organisms
-consumers rely on organisms for nutrients and energy
-carnivores, scavengers, decomposers, herbivores, omnivores, detritivores
In Your Notebook
Difference bewteen photosynthesis and chemosynthesis
-energy used from sunlight
-plants use process to make food
producers use chemical energy
used with no light such as deep under the sea
Bacteria are important members of the living community in Narragansett Bay. How do you think the bacterial communities on the floor of the bay might be linked to its consumers?
