An organism consumed by the predator.
When both members of different species benefit equally.
When two or more organisms are forced to compete for the same resources due to a shortage of resources.
- The size of an individual species in the same geographical area at a certain time.
- E.g Humans in Russia
- The population of mockingbirds in the forest
When a population experiences an accelerated growth in population. This usually produces a J-shaped curve when the population is graphed against time.
- The size of a population that can be nurtured and supported imminently by the resources and conditions present in a current ecosystem.
- The population is at a balanced stage (equilibrium).
The balance and steadiness of two opposing forces.
- How an organism occupies is place in the ecosystem with all the necessary biotic and abiotic factors.
- The resources an organism uses in the ecosystem.
- The abiotic factors that are used by the organism.
- The biotic interactions it has with other organisms.
- E.g A brown bat uses resources such as the insects it eats and the cave it uses to roost.
- The biotic niche for the brown bat are the insect that it consumes and the competitors it has such as the nighthawk.
- The abiotic relationships it has are the caves it uses for nesting.
Use of land and resources that does not deplete its resources and does not inflict long-term damage and harm upon that ecosystem, or affect the biodiversity of that ecosystem.
- The amount of time to takes for a population to double in size.
A measurement of how an individual of a population consumes resources, energy, land production, and waste production on the environment.
The benefits and positive incentives experienced by all organisms that are provided by sustainable ecosystems.
- The metamorphosis that occurs in a land where it turns from a non-desert land into a desert.
- This usually occurs because of climate change, and unsustainable use of water.
A factors the restricts the growth, spread (distribution), or amount of a population in an given ecosystem.
An organisms that kills other organisms (usually for survival).
- An organism whose niche is dependent on a close association with a larger host animal.
- A form of tourism that utilizes the natural beauty of nature.
- It involves recreational activities provided by sustainable ecosystems.
- The broad concept of making resources last as long as possible.
- It has three pillars:
- And Environmental.
- The opposite of sustainable use.
- Instead of using resources at a rate where they will be replenished by nature, unsustainable use pushes an ecosystem far beyond the regular normal capacity.
