Answer 1

Add native plants to a suburban garden because you are adding already flourishing wildlife

Sea Urchins are primary consumers because they eat the kelp

Sun -> Grass -> Rabbit because grass lives off of photosynthesis from the sun and rabbit eats the grass

I think there would be more biomass in grass because there is a lot more spread throughout the savannah while elephants are way bigger there is less of them.
