You okay baseball in a field where the grass is mowed all summer. What type of succession would occur if no one mowed the grass at all?

secondary succession

Explanation:

The kind of succession that will occur if no one mowed the grass at all is secondary succession.

Succession generally refers to a gradual change in the structure of a community over a period of times. Succession could be primary or secondary.

Primary succession occur when a site that has not held any form of life before gets colonised by a new life. The new lives are referred to as pioneer species.

Secondary succession occur when a community that already has lives in it experiences a regime of disturbance. The structure of the community will change in response to the disturbance.

Both primary and secondary succession eventually lead to a relatively stable community, otherwise known as climax community.

In this case, a baseball field that normal gets mowed every summer stops getting mowed. the community will experience secondary succession and keep changing till a level is reached where the structure hardly changes again. This level is the climax community.

the answer for this question would be d. glaciers
