Autotrophs

Organisms that capture energy from non-living sources and convert it into forms living things can use

Primary Producers

First producers of energy rich compounds that can be used later by other organisms; all life depends on them.

Photosynthesis

Process used by autotrophs to capture light energy and use it to power chemical reactions (e.g., Carbon dioxide + Water + Light → Glucose + Oxygen)

Life Without Light

Some organisms can live in total darkness, utilizing other energy sources besides sunlight

Chemosynthesis

Chemical energy is used to produce carbohydrates

Example environment for Chemosynthetic primary consumers

Ocean vents

Where Chemosynthetic Bacteria live

Earth's Crust, Underground Streams, Underground Caves, Mud of Tidal Flats

Consumers

Organisms that cannot get energy directly from the environment

Heterotrophs

Organisms that obtain food by consuming other living things

Consumers

Organisms that rely on other organisms for energy and nutrients

Carnivores

Eat meat

Herbivores

Eat plants

Omnivores

Eat both plants and meat

Scavengers

Eats carcasses of dead animals

Decomposers

Feeds by chemically breaking down organic decaying matter

Detritus

Small pieces of dead and decaying plant and animal remains

Detritivores

Feed by consuming detritus and sometimes decomposers

Primary source of energy for most life on Earth

Energy from the sun

Parasitism Relationship

The parasite benefits while the host is harmed

Mutualism Relationship

Both organisms are benefiting

Commensalism Relationship

One organism is benefiting while the other is neither harmed nor helped.
