the greenhouse effect, climate change
caused by humans = climate changes
natural occurrence = greenhouse effect

List 3 abiotic factors AND 3 biotic factors that you see.
biotic factors - grass, animals, trees, flowers, etc.
abiotic factors - mountain, sky, rocks, etc.
500
How does a species reaching it's carrying capacity affect population growth?
it will cause the species population to decline, as their environment cannot support so many of them

Whats the difference between climate change and global warming?
Global warming mainly refers to the changing of global temperatures due to the abundance of greenhouse gases int he atmosphere. Climate changes refers to the constant changes in temperature, rainfall, wind, etc. over a long period of time.
