Heterotrophs

It is an organism that cannot fix carbon and uses organic carbon for growth.

Heterotrophs uses organic carbon for growth.

Autotrophs

An organism that produces complex organic compounds from simple substances present in its surroundings.

Autotrophs produces complex organic compounds.

Photoautotrophs

An organism, typically a plant, obtaining energy from sunlight as its source of energy.

Photoautotrophs obtain energy from sunlight.

Chemoautotrophs

An organism that obtains energy through chemical process.

Chemoautotrophs obtains energy through chemical reactions.

Cell respiration

Both autotrophs and heterotrophs carry out chemical reactions that release the free energy of organic compounds.

Cell respiration release free energy of organic compounds.

Producers

Producers

Autotrophs, which produce food other organisms use.

Producers make food that consumers use to make energy.

Consumers

Heterotrophs consume plants and other organisms for food.

Consumers consume things that producers made.

Decomposers

Decomposers

Bacteria, fungi, and other heterotrophs that break down and use dead plants and animals for food.

Decomposers get energy from dead plants and animals. Ex)mushroom.

Biotic

Produced by life or living organisms.

Biotic is produced by living organisms.

Abiotic

Nonliving, which is a nonliving physical and chemical attribute of a system.

Abiotic is contrast to biotic. ( nonliving)

Ecosystem

Ecosystem

The biotic and abiotic components of a particular place make up an ecosystem.

Ecosystem always rotate. Abiotic+Biotic

Habitats

Places where particular organisms live.

Habitat is where organisms live.

Biosphere

It contains many ecosystems.

Coral reefs, deserts, marshes,a d forests.

Energy

Energy is often stored by cells in biomolecules.

Energy is necessary to our life.

Chemical energy

Organisms store energy in the organic molecules from which the organisms are made.

We use chemical energy to live.

Free energy

The portion of the chemical energy that is available to do work.

Free energy is a type of chemical energy.

Heat energy

A form of energy which transfers among particles in a substance.

Heat energy is related to temperature.

First law of thermodynamics

Energy cannot be created or destroyed.

Energy cannot be destroyed or created.

Second law of thermodynamics

Systems tend to change in a way that increases the disorder.

It tends to change a way that increases the disorder.

Entropy

Systems tend to change in a way that increases the disorder.

Entropy= disorder.

Enzymes

All living cells contain specialized proteins.

Enzymes are type of proteins.

Actives site

Specific reaction catalyzed by an enzyme depends on a small area of its tertiary structure.

Actives site is a part of tertiary structure.

Substrate

The close fit of the starting molecules.

Substrate= close fit of the starting molecules.

Metabolism

All the chemical activities and changes that take place in a cell or an organism.

Metabolism is all the chemical activities.

Synthesis

Building of reactions.

Synthesis=reactions.

Decomposition

Breaking down reactions.

Decomposition= breaking down.

Biosynthesis

Consumes free energy.

Biosynthesis... Use free energy.

Oxidation

Oxidation

Certain bonds are broken and rearranged.

Oxidation - broken and rearrange.

ATP

ATP

Adenosine triphosphate.

ATP energy that is produced after chemical reaction.

Digestion

The processes that break down food are known collectively

We digest food by using all chemical reactions and organs.

Pepsin

Active protein- digesting enzyme

Pepsin= active protein.

Small intestines

Small intestines

They absorb energy from foods that we eat.

It is 6m long.

Salivary amylase

Carbohydrate digestion begins in the mouth with the action of an enzyme.

It is in our mouth. It helps us digest our food.

Lipase

Fat-digesting enzyme.

Enzyme that helps you digest fat.

Villi

Villi

The surface area of the intestinal lining is increased tremendously by millions of small fingerlike projections.

Fingerlike projections. It's in the small intestine.
