Definitions
the interaction between living organisms and their physical environment, including the flow of energy and nutrients.
Ecosystem
energy
This type of symbiosis occurs when two organisms benefit from their interaction.
Mutualism
What is deforestation?
Clearing of forests for agriculture or development
The home where an organism lives.
Habitat
In a food web, this type of organism is typically found at the bottom of the chain, producing its own food through photosynthesis.
Producer
In this type of symbiotic relationship, one organism benefits, while the other is neither helped nor harmed.
Commensalism
What are two natural impacts on the ecosystem?
1. Wildfires
2. Flooding
3. Drought
A population is a group of organisms of the _ _ _ _ species that live in the _ _ _ _ area and interact with each other.
same
An organism that feeds on primary consumers is known as this in a food chain.
Secondary consumer
The relationship between a lion and a gazelle is an example of this type of symbiosis.
Predation
Overcropping refers to the practice of planting crops on the same land too frequently, without allowing enough time for the soil to recover. What affect would this have on the soil?
This can lead to soil degradation, reduced fertility, and the depletion of essential nutrients in the soil.
all the different populations of organisms (plants, animals, and other species) that live and interact in the same area.
A community
In a simple food chain, grass is eaten by a rabbit, which is then eaten by a fox. In this chain, the rabbit is classified as this trophic level.
Primary consumer
In this relationship, one organism benefits at the expense of the other, often harming the host.
Parasitism
Aboriginal Australians have used these two sustainable practices to manage ecosystems—one involves controlled use of fire to promote plant growth and prevent large wildfires, and the other ensures healthy fish populations by following seasonal patterns and using specific fishing methods.
Firestick farming and fish trapping
The position an organism occupies in a food chain or food web.
Trophic level
In a food chain, energy decreases as you move up trophic levels. This is the approximate percentage of energy passed on from one trophic level to the next.
10%
The relationship between cleaner fish and certain species of sharks, where the cleaner fish eat parasites from the shark’s skin, is an example of this.
Mutualism
Give 2 affects flooding has on biodiversity?
1. Destroy habitats - animals lose their shelter and food.
2. Soil Erosion - washing away of plants leading to the loss of vegetation.
3. Water Quality - contamination of water sources with pollutants, chemicals, and debris making water unsafe for plants and animals
