Ecosystems: Abiotic Factors

Ecosystems support lifeLiving things depend on the environment

You would not find a kangaroo in the Arctic and you won’t find a polar bear in Australia.

Each of these organisms is suited to a certain environment.

The kangaroo and the polar bear are able to survive despite the harsh condition of their surroundings.

Vocabulary Words

abiotic factor examples

1. temperatureTemperature influences where organisms can live. Temperatures on Earth vary enough that humans can’t live everywhere comfortably.

abiotic factor examples 2. water

All life on Earth requires water. Most organisms are made mostly of water. Every ecosystem must contain some water to support life.

abiotic factor examples 3. Sun

The Sun is the source of almost all energy on Earth. The Sun provides warmth and light, and many plants use sunlight to make food.

abiotic factor examples 4. atmosphere

The atmosphere is a layer of gases that surrounds Earth. Made of 78% Nitrogen, 21% Oxygen, and 1% trace gases. Provides living things with oxygen and protects them from certain harmful rays from the Sun.

abiotic factor examples

5. climate Climate describes average weather conditions in an area over time. Weather conditions include temperature, moisture, and wind.

abiotic factor examples 6. soil

Soil is made of bits of rocks, water, air, minerals, and the remains of once-living things. Provides water and nutrients for the plants we eat and is home for many organisms, such as insects, bacteria, and fungi.

These nonliving parts of the environment affect all living things. If either a biotic or abiotic factor is disturbed, other parts of the ecosystem are affected (ex: Global Warming).

Ecosystems. Ecosystem: All the organisms in a community plus abiotic factors ecosystems are transformers of energy& processors of matter. Ecosystems.

Chapter 54 Ecosystems. Ecosystems are all of the organisms living in a community along with the abiotic factors with which they interact. Ecosystems can.

EXPLORING MARINE ECOSYSTEMS All ecosystems contain biotic and abiotic factors Biotic = living features Abiotic = non-living physical features Relationship.

Ecosystems and the Relationships in Them!. Today’s Objectives Explain the interaction of biotic and abiotic factors in an ecosystem – Explain why ecosystems.

AQUATIC BIOMES. Biomes- Groups of ecosystems with organisms adapted to particular abiotic factors. So, abiotic factors determine the biome! Aquatic Biomes.
