• Less sediment flowed into the river because the fire heated up the soil and made it drier. 
• The amount of vegetation increased and less sediment flowed into the river because the fire produced ash that mixed with the soil. 
• More sediment flowed into the river because the fire destroyed most of the vegetation holding the sediment in place. 
• More sediment flowed into the river because the fire disrupted animal habitats and caused animals to leave the area.

• Increased gill surface area has allowed the cichlids to change their diet and avoid competing with the Nile perch. 
• Increased gill surface area has allowed the cichlids to be camouflaged and avoid being eaten by the Nile perch. 
• Increased gill surface area has allowed the cichlids to leave Lake Victoria and establish populations in nearby bodies of water. 
• Increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.
