A high degree of biodiversity refers to the richness of different species in an area, especially in an _____
ecotone
What is the biosphere

eg: population- all of the vegetables of 1 type (i.e. all of the carrots)community-all living things in the garden (all plants and any animals)
What are two examples of biotic factors and twoexamples of abiotic factors thatcan affect the lives of trees inan area?
Biotic: other living plants (competing for nutrient in soil)- Animals (i.e. deer may eat parts of the tree)Abiotic: SunlightRain(wind)
