Managing and manipulating plant life.

their hooves shape the ground and make holes

Augmenting soil health.

2024-09-10 14:02:10 UTC

alterate soil in the environment with there hooves

2024-09-10 14:03:41 UTC

grazing patterns help the population of insects and influences natural fires

their grazing patterns created successful vegetation

2024-09-10 14:03:42 UTC

they aerate thee soil

Birds feed on insects disturbed by bisons steps.

They reproduce and increase the population

2024-09-10 14:04:07 UTC

2024-09-10 14:04:10 UTC

They allow birds to feed off of the birds that burrow into their fur

their dead body's make indents into the ground

Bison grazing helps to control the growth of vegetation

they spread seeds

2024-09-10 14:06:06 UTC

it equals to both things fighting over the food

2024-09-10 14:06:06 UTC

when they make wallows the wallows fill with water and make water sources

2024-09-10 14:06:23 UTC

2024-09-10 14:06:42 UTC

It creates a more complex food chain

2024-09-10 14:06:51 UTC

we can learn that if you take away one species that the other will thrive and over populate until it is brought back

less food to go around especially when they both eat the same food

2024-09-10 14:07:19 UTC

it helps keep population down with the ones that are over populated

2024-09-10 14:07:29 UTC

2024-09-10 14:07:36 UTC

We can learn a good way to maintain the ecosystem. It helps the population balance out and returns the ecosystem to normal. It could help grass growth.

They decrease the insect population

2024-09-10 14:07:37 UTC

Adds a food sources

2024-09-10 14:07:49 UTC

They create new grazing lands

2024-09-10 14:07:55 UTC

2024-09-10 14:08:04 UTC

life is rough. two predators fight for same food source

2024-09-10 14:08:18 UTC

They wallow in the mud and create breeding grounds for birds
