Microhabitat and Biome Notes

Read Only

• These notes will show the levels of organization within the environment. – The next slide will show you a flow map that diagrams the overall idea first.

– Each of the slides after that will give you notes about each individual portion of that flow map.

• For this unit, you will be required to… Observe and describe how

different environments

(including microhabitats in schoolyards and biomes)

support different varieties of organisms.

Levels of Organization Examples

Habitat Microhabitat

Biosphere:

life-supporting portions of Earth composed of air (atmosphere), land (lithosphere), and water (hydrosphere).

• Organisms live on either the hydrosphere or the lithosphere.

• The atmosphere is part of both of these spheres Draw and label this picture

Biome A large geographic area characterized by climate and specific plants and animals.

Desert Biome Tundra Biome Rainforest Biome Forest Biome Marine Biome

5 Main Types of Biomes Land Biomes

1. Desert 2. Forest Includes Tropical Rainforest and Temperate Forest (aka the Taiga) 3. Grassland Includes Savanna Grassland and Temperate Grassland 4. Tundra

Water Biomes

5. Aquatic Includes Freshwater (lakes; rivers) and Marine (ocean; estuaries)

Distance from the equator determines temperature and amount of precipitation. These abiotic factors then affect the biotic factors that exist in those regions.

aka mini biomes

Eco-Region -

a large area with distinctive landforms, characteristic plants and animals also receiving uniform solar radiation and moisture (rainfall) We live in the Temperature Grasslands

Biome

part of the

world

and the Prairie

Eco-Region

part of our

state.

Ecosystem

All

the LIVING (biotic) and NON-LIVING (abiotic) things in a given area.

Bio = life (biotic = living) A = not ( a biotic = not living )

Biotic Components Abiotic Components

Precipitation aka temperature

Habitat

The place where an organism lives;

habitat = home

– A sustainable (able to be continued) habitat must include all characteristics that support life:

food, water, shelter and enough space.

Though they are not naturally created, organisms can also live in artificial habitats such as a fish tank or playground

Home Small

Micro habitat

Immediate, localized environment of organism

(part of a larger habitat)

Examples: – Owl’s hole in a tree – Beehive – Insect on a leaf – Mushrooms on a rotting log – Lichen growing on a rock

Microhabitats and Symbiotic Relationships

READ ONLY Many microhabitats contain relationships between different organisms where one or both benefit from the other. These are called

symbiotic

relationships.

Example: clown fish and sea anemone

The anemone provides a microhabitat (food, water, shelter and space)for the clownfish and the clownfish provide fertilizer to the plant as well as protection.
