Ecosystems Review 1: Intro + Photosynthesis + Respiration

What are ecosystems?

• A place where the organisms and their physical surroundings form an environment that is different from other environments nearby.

• The factors that affect an organism's changes of survival over its lifetime.

• Non-living, physical factors.

• Living factors.

What two factors affect ecosystems?

• Environmental and Biological Factors

• Abiotic and Biotic Factors

Define an environment?

• A place where the organisms and their physical surroundings form an environment that is different from other environments nearby.

• The factors that affect an organism's changes of survival over its lifetime.

• Non-living, physical factors.

• Living factors.

What are abiotic factors?

• Non-living, physical factors such as water, temperature, fire, light, soil type and oxygen levels.

• Living factors such as competition, predation, mutualism, paratism, commenalism and adaptations.

• Non-living, physical factors such as competition, predation, mutualism, paratism, commenalism and adaptations.

• Living factors such as water, temperature, fire, light, soil type and oxygen levels.

What are biotic factors?

• Non-living, physical factors such as water, temperature, fire, light, soil type and oxygen levels.

• Living factors such as competition, predation, mutualism, paratism, commenalism and adaptations.

• Non-living, physical factors such as competition, predation, mutualism, paratism, commenalism and adaptations.

• Living factors such as water, temperature, fire, light, soil type and oxygen levels.

What is competition?

• When different organisms try to obtain the same resource, which may only exist in limited amounts.

• When organisms live closely together and both benefit. E.g. Pollination between bees and flowers.

• When one organism benefits from the relationship, and the other is harmed.

• When one organism kills and eats another, the attacker is called the predator and the one being eaten is called the prey.

• When one organism benefits from the relationship and the other is unaffected.

What is mutualism?

• When different organisms try to obtain the same resource, which may only exist in limited amounts.

• When organisms live closely together and both benefit. E.g. Pollination between bees and flowers.

• When one organism benefits from the relationship, and the other is harmed.

• When one organism kills and eats another, the attacker is called the predator and the one being eaten is called the prey.

• When one organism benefits from the relationship and the other is unaffected.

What is predation?

• When different organisms try to obtain the same resource, which may only exist in limited amounts.

• When organisms live closely together and both benefit. E.g. Pollination between bees and flowers.

• When one organism benefits from the relationship, and the other is harmed.

• When one organism kills and eats another, the attacker is called the predator and the one being eaten is called the prey.

• When one organism benefits from the relationship and the other is unaffected.

What is parasitism?

• When different organisms try to obtain the same resource, which may only exist in limited amounts.

• When organisms live closely together and both benefit. E.g. Pollination between bees and flowers.

• When one organism benefits from the relationship, and the other is harmed.

• When one organism kills and eats another, the attacker is called the predator and the one being eaten is called the prey.

• When one organism benefits from the relationship and the other is unaffected.

What is commensalism?

• When different organisms try to obtain the same resource, which may only exist in limited amounts.

• When organisms live closely together and both benefit. E.g. Pollination between bees and flowers.

• When one organism benefits from the relationship, and the other is harmed.

• When one organism kills and eats another, the attacker is called the predator and the one being eaten is called the prey.

• When one organism benefits from the relationship and the other is unaffected.
