Abiotic |
A physical or nonliving thing in the ecosystem
|
Soil, minerals, water
|
|
|
Autotrophs
|
An organism that forms it's own food molecules from abiotic materials
|
Most plants are autotrophs due to photosynthesis.
|
|
|
Biotic
|
Living organisms in the ecosystem
|
Animals, humans, plants, and insects are biotic.
|
|
|
Biosphere
|
The outer portion of Earth-air water, and soil- where life is found
|
We live in the biosphere.
|
|
|
Cell Respirtation
|
The series of chemical reactions by which a living cell breaks down carbohydrates and obtains energy from them.
|
When we digest food, our cells are doing this.
|
|
|
Chemautotroph
|
An organism that must consume organic compounds for energy and carbon
|
Plants are chemoautotrophs because they have to make their own food to survive.
|
|
|
Consumers
|
Organisms that consume other organisms for food.
|
Humans are the biggest consumers on the planet.
|
|
|
Producers
|
Organisms that produce their own food.
|
Again, plants are examples of producers.
|
|
|
Heterotrophs
|
Organisms that obtain their energy by consuming other organisms, living or dead.
|
Lions, tigers, and bears are heterotrophs because they hunt other animals.
|
|
|
Photoautotrophs
|
Autotrophs that use energy from sunlight to synthesize organic compounds from carbon dioxide and water.
|
Any autotroph that is capable of performing photosynthesis is a photoautotroph.
|
|
|
Decomposers
|
Heterotrophs that break down and use dead plants and animals for their food
|
Bacteria and fungi are decomposers.
|
|
|
Ecosystem
|
A biological community with it's abiotic parts
|
Earth as a whole is a giant ecosystem, from its people to its oceans.
|
|
|
Habitats
|
Places where particular organisms live.
|
A fox's den is its habitat.
|
|
|
Digestion
|
The processes that break down foods
|
We do this every time we put food or liquids into our bodies
|
|
|
Salivary Amylase
|
An enzyme in saliva that begins the digestion of starch
|
Breaks down carbohydrates; starting in your mouth.
|
|
|
Pepsin
|
A protein splitting enzyme secreted by the gastric glands in the stomach
|
Breaks down proteins in the stomach
|
|
|
Villi
|
A finger like projection of the small intestine that increases surface area for absorption and digested food
|
In the small intestine, helps with collection digested foods
|
|
|
Lipase
|
A fat-digesting enzyme
|
This would help digest the twinky you just ate.
|
|
|
Small intestine
|
Main functions age digestion and absorption of food
|
It helps you pass those twinkies you just ate
|
