Which symbiotic relationship is when one organism benefits and the other is not impacted (positively or negatively)?

• Predation

• Mutualism

• Commensalism

• Parasitism

Cattle egrets forage (feed) in fields among cattle. The egret gets easy access to flying insects stirred up by the cattle, and the cattle don't care if they are there or not.

• mutualism

• commensalism

• competition

• parasitism

A species that has a disproportionately large effect on community structure relative to their abundance.

• Pioneer Species

• Invasive Species

• Keystone Species

• Foundation Species

Which symbols best describe commensalism?

• +,+

• +,-

• +0

• 0,0

What is true about sustainability?

• Having a small number of species increases biodiversity

• Sustainability is how organisms change over time

• Sustainability is how much rainfall and sunlight an ecosystem receives

• The more different types of species you have (biodiversity) the better an ecosystem can sustain itself
