Interactions Within Ecosystems - Science Review 1 - 2021

HABITAT
Is the place where biotic organisms live and can find everything they need to survive. Habitats provide all the conditions needed to support and sustain life, like:

ECOSYSTEM
A community or group of living organisms that interact and live with each other in a specific environment. It's the interaction/relation between biotic and abiotic factors in a habitat.

What is the size of an ecosystem?

PHOTOSYNTHESIS
It's the process where plants produce their own food. The chlorophyll is responsible for absorbing sunlight, and it also makes the plants' leaves green.

What would be the word equation for the photosynthesis process?

CELLULAR RESPIRATION
It's the process where plants "breathe" oxygen, and combine it with glucose to create energy.

What would be the word equation for the cellular respiration?

FOOD CHAIN
A linear diagram made to show the flow of energy through biotic elements and represent how living things are connected to each other by the food they eat. The arrows always point from the food source toward the organism the energy is flowing to, and not the other way around. Food chains are organized in trophic levels - trophic means: relating to feeding and nutrition.

What are these levels, and what are their definitions?

FOOD WEB
Is the interconnection between many food chains from the same habitat/ecosystem.

Can the extinction of one type of living thing affect a whole food chain?

ECOLOGICAL SUCCESSION
Process where we form a community (place where different species interact with each other). The primary succession is when we form an ecosystem for the first time, it's the development of a habitat from scratch. The secondary succession is when an ecosystem suffers a disaster or devastation, and has to be re-formed.

What are the steps of a succession?

CARBON CYCLE
Process in which the carbon dioxide is removed from the atmosphere, and then released again.

What causes the removal and the release of carbon dioxide into the atmosphere?
