What is photosynthesis?
Photosynthesis is the process in which plants take the energy from the sun’s rays and converts it into chemical energy.
What is carbon dioxide?
Carbon dioxide, also known as CO 2, is the process in which carbon and oxygen bond together, which traps greenhouse gas and is changing the climate of the Earth.
What is light energy?
Light energy is the only form of light that we can see. It can be converted into other types of energy, such as heat energy.
What is glucose?
Glucose, also known as blood sugar, is a source of energy for plants and animals. It is also a carbohydrate.
What are chloroplasts?
Chloroplasts are food producers of cells. They are commonly found in plants or bacteria, such as algae.
What is chlorophyll?
Chlorophyll is a green pigment found in plants. It is used for plants to help it make food, and is used as medication for humans, helping to treat pancreatic, for example.
What are the symbiotic relationship?
There are three types of symbiotic relationships:
MUTUALISM - when both organisms benefit
PARASITISM - one organism benefits at the expense of another
COMMENSALISM - one organism benefits, while the other is neither helped nor harmed
What is an environment?
An environment is the surroundings in which an organism lives, including living and non-living things that can help or do damage to that environment.
What is global warming?
Global warming is the gradual heating of the Earth’s oceans, surface, and atmosphere. This is caused by CO 2 trapping greenhouse gas.
What is a habitat?
A habitat is an area in which an organism lives.
What is instinct?
Instinct is something you do naturally, without having to learn it or think about it.
What is migration?
Migration is an organism moving from one place to the next.
What is an organism?
An organism is a plant, animal, fungus, bacterium, or protest.
What does it mean to pollute?
To pollute something means to introduce something harmful to an environment.
What is a stimulus?
A stimulus is something that cases an organism to react to something.
What is a response?
A response a reaction to a stimulus.
What is internal?
Internal is inside.
What is external?
External is outside.
What is the process of photosynthesis?
The process of photosynthesis:
- the sun’s rays are directed towards a plant
- the plant absorbs the energy from the sun and converts it into chemical energy
This process occurs in plants and algae. It happens because the plant is trying to get energy.
What is internal stimuli?
Internal stimuli is a reaction to something inside the organism’s body, for humans, for example, internal stimuli would be having a virus, or eating food poisoning.
What is external stimuli?
External stimuli is a reaction on the outside of the organism’s body. For example, with humans (again), when we are cold, we shiver, and when we are hot, we sweat.
What are abiotic factors?
Some abiotic factors in an organism’s environment are things that are not living, such as rocks.
What are biotic factors?
Some biotic factors in an organism’s environment are things that are living, like trees and grass.
What is a food chain?
A food chain shows what nutrients and energy animals get from the food they eat. For example, a bunny eats grass, and the fox eats the bunny, while the fox is getting nutrients from both the bunny and plant.
