Date Session # Activity Page # Objective: Interpret various text to describe ecosystems and organisms’ roles in those ecosystems using biotic and abiotic components. Date Session # Activity Page # 4/25-26 Components of an Ecosystem 5 Ocean Ecosystems 6 Habitat & Niche 7 Homework: Complete ecosystem & niche tables EOG review packet: Chem Unit question 6-10

8.L.3 Understand how organisms interact with and respond to the biotic and abiotic components of their environment 8.L.3.1 Explain how factors such as food, water, shelter, and space affect populations in an ecosystem. 8.E.1.Understand the hydrosphere and the impact of humans on local systems and the effects of the hydrosphere on humans. 8.E.1.2 Summarize evidence that earth’s oceans are a reservoir of nutrients, minerals, dissolved gases and life forms: Estuaries Marine ecosystems Upwelling Behavior of gases in the marine environment Deep ocean technology and understandings gained.

Biotic and Abiotic Environment Biosphereecosystem  community  population  individual

Components of an Ecosystem Ecosystem a system formed by the interaction of a community of organisms with their environment. This includes biotic and abiotic factors in the environment Community Community all the populations that live in an area at the same time Population Population all the organisms of a species that live in the same place at the same time. Population Individuals

Biosphere: all the ecosystems on earth Ecosystem: a system formed by the interaction of a community of organisms with their environment. This includes biotic and abiotic factors in the environment

Community: all the populations that live in an area at the same time Population: all the organisms of a species that live in the same place at the same time. They can be described based on their size, distribution or density. species: share characteristics and can breed with each other

Ocean Ecosystems Login to to the Ocean Ecology Blendspace. Using slides 1-9, read the brief description of each ecosystem and watch the videos. Complete the data table in your notes using the information on the slides. Ecosystem Description Abiotic Components Biotic Components Estuary Coral Reef Kelp Forest Hydrothermal Vents

Within an ecosystem, each species has a… Habitat: the place where an organism lives. It supplies all the biotic and abiotic factors the organism needs to survive. Niche: an organism’s role/”job.” what it eats, how it eats and how it lives… If the niche of one organism overlaps the niche of another organism, you have competition!
