• Symbiosis

A frog eats a fly. The frog and fly are demonstrating ________.

• mutualism

• competition

• predator/prey

• parasitism

Image "B" shows more biodiversity than image "A". Why?

• Because "B" shows more different species than image "A"

• Because image "B" has less different species than "A"

• "A" has a greater number of same species plants so this statement is wrong.

• Both images show the same biodiversity

Which habitat exhibits the greatest biodiversity?

• A habitat with 15 different species with about 300 individuals each
• A habitat with 10 different species with about 75 individuals each
• A habitat with 4 different species with about 150 individuals each
• A habitat with only one species with about 2000 individual
