Easter Islands Discovered in 1722

Easter Islands Discovered in 1722 Treeless Island

Easter Islands Discovered in 1722 Treeless Island After cutting down all trees, loss of trees led to erosion, no materials for making boats or fishing  population began declining

Ecosystem:

Ecosystem: all the interacting parts of a biological community and its environment

Sustainable ecosystem:

Ecosystem: all the interacting parts of a biological community and its environment Sustainable ecosystem: an ecosystem that is capable of withstanding pressure and giving support (it must endure and support)

Parts of an Ecosystem Biotic:

Parts of an Ecosystem Biotic: the living parts of an ecosystem Abiotic: the non-living parts of an ecosystem

Parts of an Ecosystem Biotic: the living parts of an ecosystem Abiotic: the non-living parts of an ecosystem

CuPS Biotic InteractionHow It Works For Biotic Interactions

CuPS Biotic InteractionHow It Works CompetitionWhen two or more organisms compete for the same resource such as food in the same location at the same time. For Biotic Interactions

CuPS Biotic InteractionHow It Works CompetitionWhen two or more organisms compete for the same resource such as food in the same location at the same time. PredationWhen one organism consumes another organism for food. The organism consumed is the prey and the consumer is the predator. For Biotic Interactions

SymbiosisMutually beneficial interaction between members of two different species For Biotic Interactions

Cycling of Matter and Earth’s Spheres

Lithosphere: the hard part of Earth’s surface

Cycling of Matter and Earth’s Spheres Lithosphere: the hard part of Earth’s surface Hydrosphere: all the water found on Earth, including lakes oceans and ground water

Cycling of Matter and Earth’s Spheres Lithosphere: the hard part of Earth’s surface Hydrosphere: all the water found on Earth, including lakes oceans and ground water Atmosphere: the layer of gases above Earth’s surface

Cycling of Matter and Earth’s Spheres Lithosphere: the hard part of Earth’s surface Hydrosphere: all the water found on Earth, including lakes oceans and ground water Atmosphere: the layer of gases above Earth’s surface Biosphere: the regions of Earth where living organisms exist

Nutrients:

Nutrients: a chemical that is essential to living things and is cycled through ecosystems

4 Types of Nutrient Cycles Water Cycle Carbon Cycle Nitrogen Cycle Phosphorous Cycle

The Water Cycle: the most vital _______ part. Condensation, precipitation, evaporation abiotic

The Water Cycle: the most vital abiotic part. Condensation, precipitation, evaporation abiotic

The Carbon Cycle

Like water, carbon moves through Earth’s spheres. Carbon dioxide, a gas, moves from atmosphere into the biosphere and back again. CO2 is returned to the atmosphere when humans burn the fossil fuels for energy

The Nitrogen Cycle

Nitrogen: 78% of atmosphere

Terrestrial Ecosystem: a land-based ecosystem Aquatic Ecosystem: a water-based, either fresh water or salt water, ecosystem

The Phosphorus Cycle

The Phosphorous Cycle Phosphorous is stored in the lithosphere (rocks and in sediment on ocean floor) Humans mine for phosphate rock  used to make fertilizers and detergents Phosphate is absorbed by plants through roots As decomposers, bacteria break down dead organisms, releasing phosphate back into soil
