Biomes

Biomes

  • Chaparral

  • Desert

  • Savanna

  • Taiga

  • Temperate Deciduous Forests

  • Temperate Grassland

  • Tropical Rain Forest

  • Tundra


Epiphytes

epiphytes


Succulents

succulents


Biotic factors

Biotic factors


Abiotic factors

Abiotic factors


Wetland

wetland

Areas where land is periodically underwater.


Plankton

plankton

Organisms that cannot swim against currents, they are drifters. The majority are microscopic.


Nekton

Nekton

  • Free swimming organisms, such as fish, turtles, and whales.


Benthos

Benthos

  • Bottom dwelling organisms, such as mussels, worms, and barnacles.

  • (Many live attached to hard surfaces)


Littoral zone

Littoral zone

  • Nutrient rich zone near the surface of a lake or pond


Benthic zone

Benthic Zone

  • The bottom of the pond or lake, which is inhabited by decomposers, insect larvae, and clams.


Eutrophication

Eutrophication

  • An increase in the amount of nutrients in an aquatic ecosystem.


Factor 1 salinity salinity the amount of dissolved salts in the water

Factor 1 – Salinity(salinity- the amount of dissolved salts in the water)

Fresh Water Ecosystem

Marine Ecosystem


Factor 2 sunlight

Factor 2 - Sunlight

  • Sunlight only reaches a certain distance below surface, so it effects the location of where photosynthetic organisms can live


Factors 3 oxygen

Factors 3 : Oxygen

  • Non photosynthetic organisms need oxygen to survive, so the amount of oxygen in an ecosystem determines how much life can be supported there.


Factor 4 nutrients

Factor 4: Nutrients

  • All organisms need nutrients to survive, but too much can be cause eutrophication


Factor 5 temperature

Factor 5: Temperature

  • Temperature controls the solubility of oxygen. As temperature increases, oxygen is less soluble.

  • Also influence the biological activity of aquatic organisms


Grouping of aquatic organisms

Grouping of aquatic organisms

  • Plankton Nekton Benthos


Ecosystems lakes and ponds

Ecosystems: Lakes and Ponds

How they form:

Naturally, where groundwater reaches Earth’s surface

Unnaturally – damming or rivers by humans or beavers


Life in a lake

Life in a lake

Life in the littoral zone

Life in the benthic zone


Biomes

Littoral zone

Benthic Zone

Bacteria

Decomposers

Fish adapted to cooler water

Insect larvae

clams

  • Rooted Plants, such as cattails

  • Further from shore – no rooted plants, instead there are phytoplankton

  • Fish

  • Insects

  • amphibians


Eutrophication1

Eutrophication

  • Eutrophic lake – a lake that has a large amount of algae and plant growth


Eutrophication2

Eutrophication


Fresh water wetlands

Fresh Water Wetlands

Marshes

Swamps

Dominated by woody plants (trees and shrubs)

-Occur on flat, poorly drained land often near streams

Species of trees depends on salinity

Birds such as wood ducks

Ideal habitat for amphibians (frogs, salamanders, etc)

Reptiles (ex. Alligator)

-Contain non woody plants (cattails)

-Tend to have low, flat lands and little water movement

-Benthic zones are nutrient rich and contain plants, decomposers, and scavengers

-Wide variety of water birds (ducks, herons, etc)

-Migratory birds

-Salinity varies(some slightly saline, some as salty as the ocean)

Environmental functions of wetlands

Environmental Functions of wetlands

  • Absorb and remove pollutants from water that flow through them

  • Control flooding by absorbing extra water when rivers overflow

  • Provide spawning grounds and habitat to fish and shellfish we consume

  • Provide habitat for native and migratory wildlife (many which are rare, threatened, and endangered)


Rivers

Rivers

  • Many originate from snow melt in mountains.

    At it’s headwaters river is cold and full of oxygen

    -As it flows down mountain it becomes warmer, wider, and slower, containing more vegetation and less oxygen

    As it flows nutrients are added to river from sediment and runoff


Life in a river

Life in a river

At headwaters

Downstream

Plants set roots in river’s rich sediment

Fish such as catfish and carp

  • – mosses anchor to rocks

  • Trout and minnows adapted to cold, oxygen-rich water
