Question

the savanna is home to a variety of plant and animal species. populations depend on and may compete for biotic and abiotic factors in this biome. select all of the interactions between biotic factors in the savanna.
a a lion pride hunts zebra.
b the yearly rainfall pattern causes wet and dry seasons.
c populations compete for food sources at the watering hole.
d the average rainfall and temperature determine the plant life that can grow in the savanna.
e herbivores such as elephants and rhinos depend on the variety of grasses that grow in the savanna.

Explanation:

• Option A: A lion pride (biotic) hunts zebra (biotic). This is an interaction between biotic factors (predation).
• Option B: Yearly rainfall pattern (abiotic) causes wet and dry seasons. This is an abiotic - abiotic interaction.
• Option C: Populations (biotic) compete for food sources (biotic) at the watering hole. This is an interaction between biotic factors (competition).
• Option D: Average rainfall (abiotic) and temperature (abiotic) determine plant life (biotic). This is an abiotic - biotic interaction.
• Option E: Herbivores (biotic) depend on grasses (biotic). This is an interaction between biotic factors (herbivory).

Answer:

A. A lion pride hunts zebra.
C. Populations compete for food sources at the watering hole.
E. Herbivores such as elephants and rhinos depend on the variety of grasses that grow in the savanna.
