Grade 9 Science - Part 2 Ecology Flashcards
What ate the 2 processes in which causes carbon to enter the atmosphere?
- Respiration from animals
2. Burning fossil fuels
What ate the 2 processes in which causes water to enter the atmosphere?
- Evaporation
2. Transpiration
Transpiration?
When water evaporates from the surface of plants
What would happen if all bacteria and fungi became extinct?
after death animals’ energy would cone to a halt and eventually everything would die off
What are the 2 complementary processes?
- Respiration
2. Photosynthesis
Why is photosynthesis and respiration known as complementary processes?
They both allows needed substances to go to living things just in different ways
Photosynthesis?
The act in which a plant creates food by converting the sun’s energy into chemical energy
Respiration?
The act in which a plant converts oxygen and glucose to carbon dioxide and water
What would happen if plants stopped their respiratory?
There would be nothing to convert our exhaled carbon dioxide to oxygen so eventually we would die of lack of oxygen
Water cycle?
First water evaporates from a wet land or transpires from plants into a cloud. Then the water condenses and transfers the water through precipitation. The water than gets absorbs into the ground creating ground water. Finally it appears back to the wet lands
Carbon cycle?
Starts out in the soil and either gets transferred through fossil fuel burning, reparation or photosynthesis. Then it transfers to a wet land where it slowly sedimentations back go the soil
What’s the word equation for respiration?
Respiration = Carbon dioxide + water
Whats the word equation for photosynthesis?
Photosynthesis = oxygen + glucose
How are similar species able to coexist with minimal competition?
This is done because organisms pf similar species go for separate pray
What are the three adaptations that pray use to avoid predators
- Scent
- Taste
- Colour
Mutualism?
The act of a species benefiting from the activity of another different species.
Commercialism?
When one organism benefits from the other without effecting it
Parasitism?
When one organism benefits while the other is harmed
Abiotic?
a non-living thing
Biotic?
a living thing
nutrient?
Food or anything that gives an organism energy
Photosynthesis?
The act of a plant converting the energy from the sun into chemical energy.
Nutrient Cycle?
The act of exchanging an organic back into the production of living matter
Cellular Respiration?
The act of a plant inhaling carbon dioxide/water and exhaling oxygen/glucose
Reservoir?
A host that can harbour pathogenic organisms without self injury but may cause harm to other individuals.
Energy Pyramids?
a pyramid that demonstrates the level of energy and where the energy goes throughout an ecosystem
Organic Matter?
The matter composed of organic remains
Competition?
a harmful interaction between 2 different species regarding food, water, and territory.
Predator?
The act of an organism that is hunting for its meal
Prey?
The act of an organism that is being hunted as a meal
Predation?
The act of a predator hunting its prey
Symbiosis?
The act of 2 organisms associating which usually results in a mutual benefit for both members
Carrying Capacity?
The max a population’s size can be before the resources start to cause the population to decrease
Limited Factor?
The factor that limits the growth, abundance, or distribution of an organisms population
Ecology?
The science that observes the relation between organisms and their environment
Ecologist?
A person that studies ecology
Ecosystem?
Everything that exist in a particular environment
Carnivore?
An animal that only consumes other animals
Herbivore?
An animal that only consumes plants
Omnivore?
An animal that consumes both plants and animals
Detrivore?
An organism that consumes other dead organism
