Oceanic ecosystems

Warm up p.70 Watch the following clip. What living things do you see? What non living things do you see? What types of habitats do you see in the clip? What are the individual animals roles in the ecosystem? https://www.youtube.com/watch?v=D3W4OCnHyCs

What is Ecology? Ecology - the study of the interactions of organisms with one another and with their environment. Ecologist – a scientist who studies ecology

Habitat & Niche Habitat is the place a plant or animal lives that provides, food, water & shelter Niche is an organism’s total way of life; it’s role or job

Vocab Squares- Habitat and Niche What is the fish’s habitat ? What is the coral’s niche? Vocab Squares- Habitat and Niche

Two Parts of an Ecosystem Biotic factors ...Twig The living parts of an ecosystem Ex.: plants, animals, fungi, Bio = living; life Abiotic factors...twig The nonliving parts of an ecosystem Ex: water, sunlight, oxygen, temperature, soil A = non; not; without Vocab Squares- biotic and abiotic

What are the biotic parts of this environment? The abiotic parts? Vocab squares: abiotic and biotic

Then what?

Organism Single living thing Can survive on its own 1 Sardine

Population A group of individuals of the same species that live together. School of Sardine

Community All the different populations of species that live together in an area –or- All of the living things (biotic factors) in an area Sardines + Swordfish + sharks

Ecosystems Made up of all the biotic (living) and abiotic (nonliving) factors that interact in a particular area. Sardines + Swordfish + sharks + water + sunlight

Biome A large region with a similar climate, and specific plant and animal communities that have adapted to that climate Terrestrial (Land) Aquatic (Water) Tropical rainforest Marine (oceans) Savanna/Grassland Freshwater (rivers & lakes) Temperate Forest Estuary Desert Taiga Tundra Mountain

Biosphere The part of Earth where life exists The biosphere includes the top portion of Earth’s crust, all the waters that cover Earth’s surface, and the atmosphere that surrounds Earth.

Ecological Organization

Levels of organization Think of San Diego’s ecosystem and create a level of organization starting with an organism.

Situation Cards Read the card at your table and talk amongst yourselves about the situation. You are going to switch roles every situation. Each card involves topics we will learn more about as the unit continues.

Example situation Pollution has been a huge factor in climate change which is increasing temperatures around the globe. This is in turn causing the Arctic ice to melt. Polar bears use this ice to catch seals. What do you think is going to happen to the polar bear population in the next 20 years?

No arctic ice With arctic ice
