I know that crab grass and weeds are examples of secondary succession.
FIRE!!!! is another example
the plants and animals
fat plants.
Soil nutrients remain in the area which enables plants to grow.
A tornado results in secondary succession. The plants on the surface are destroyed, but buried seeds generally stay in place and the soil remains mostly intact.
It is crab grass.
the plants and animals
Secondary succesion is the succession that occurs after the initial succession has been disrupted, and some plants and animals still exist. It is usually faster than primary succession.
fat plants.
The grass and small plants come first, then more plants, then larger plants like trees, next come large animals until you finally have a complete ecosystem.
the difference between primary and secondary succession is that primary succession is the wipeout of something and then secondary succession is the regrowth.
Primary succession is when living things colonize an area where there were no living things to begin with. For example, after a glacier moves away. Secondary succession is the regeneration of a place that did have colonization. For example, after a forest is cut down.
Soil nutrients remain in the area which enables plants to grow.

A tornado results in secondary succession. The plants on the surface are destroyed, but buried seeds generally stay in place and the soil remains mostly intact.
Secondary succession is faster than primary succession because soil is already there and the soil usually contains many seeds.

Primary consumers feed on producers (plants) and secondary consumers feed on primary consumers. For example, rabbits are primary consumers because they feed on vegetation. Foxes are secondary consumers because they feed on rabbits.
