What is a food web
Feeding Relationships that are possible in an ecosystem.
What would happen if we don't recycle?
We destroy natural habitats. As it is, our earth cannot cope with the current rate of destruction.
What things are in response to stimuli？
Smell taste, light, taste, light, smell and touch, etc
Give me an definition of ecosystem.
It is an environment including a commmunity plus non-living factors.
How are ecosystems destroyed by humans? Give me two examples.
By cutting trees and flooding.
What is a trophic level？
Each step in the transfer of energy through or web in an ecosystem.
How does recycling benefit the planet?
Recycling reduces the need to grow, harvest or extract new raw materials from the Earth.
What are the seven characteristics that have life?
1.Organisms have reproductive roles.
2.Organisms have metabolic effects.
3.Organisms can grow and develop.
4.Organisms are stressful.
5.Organisms are characterized by genetic variation.
6.Organisms can adapt to and influence the environment.
What are abiotic and biotic factors (give me some examples)
1.Biological factors; humans, insects, wildlife, birds, bacteria.
2.Abiotic factors; soil, rainfall, humidity, temperature, pH, climate
What are some examples of egg eaters? Give 2 examples

Explain the relationship between stimulus and response？
stimulus-response theory, idea that learning and be haviour can be explained by interactions between stimuli and the responses they evoke.
How do we know humans are causing climate change? Give us 2 examples
humans are burning fossil fuels, releasing huge amounts of carbon pollution and trapping more and more heat in the atmosphere.
What makes a food web more stable?
The flow of energy in a food web is always unidirectional. In a food web, the supplies of food never end
Disadvantages and advantages of recycling.
Disadvantage- More Energy Consumption and Pollution. Advantage- Recycling reduces waste sent to landfills and incinerators
