Question: What Type Of Vegetation Would You Expect To Find On An Abandoned Farm?

What type of succession would you expect to find in the abandoned farmlands?

In addition, through a process called old-field succession, farmland that has been abandoned may undergo secondary succession.

What type of vegetation would you expect to find on an abandoned farm that has remained undisturbed 450 years?

tall, mature oak trees.

What type of vegetation would you expect to find on a newly formed volcanic island?

On newly created volcanic islands, for example, after the rock cools, seeds blown by the wind may lodge in crevices, germinate, and take root. Often these first colonizing plants are weedy species, such as fast-growing grasses and lichens, that do not grow tall but do reproduce quickly.

What type of succession occurs after a natural process such as flood?

Secondary succession, the more common type of succession, occurs on a surface where an ecosystem has previously existed. It occurs in ecosystems that have been disturbed or disrupted by humans, animals, or by natural processes such as storms, floods, earthquakes, and volcanoes.

What are the stages of forest succession?

Forest ecologists recognize four phases of forest succession, or what is sometimes called forest development. These phases are: (i) stand initiation, (ii) stem exclusion, (iii) understory reinitiation, and (iv) steady state.

What is the difference between primary and secondary succession?

In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.

Where would you most likely find nitrogen fixing bacteria?

Where would you most likely find nitrogen – fixing bacteria? On the roots of legumes. Why are forest fires good for ecosystems? Forest fires allow some trees to release their seeds, by clearing away deadwood, and by encouraging new growth.

What do deep ocean bacteria use to make their food?

Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis. These minerals include hydrogen sulfide, which the bacteria use in chemosynthesis. Autotrophic bacteria that produce food through chemosynthesis have also been found at places on the seafloor called cold seeps.

Which type of volcanic eruption is the most explosive?

The largest and most violent of all the types of volcanic eruptions are Plinian eruptions. They are caused by the fragmentation of gassy magma, and are usually associated with very viscous magmas (dacite and rhyolite).

Why are lichens successful pioneers?

Why are lichens successful pioneers? Lichens are successful because they grow on bare rock. Also, they are made up of algae that provides food and energy through photosynthesis that attach to rock and capture moisture. Algae and other organisms grow, reproduce, and die and gradually fill pond with organic matter.

What does primary succession end with?

Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.

What are some possible causes of succession in ecosystems?

Possible answers include, human activity, such as logging and deforestation leading to succession. Large changes in the vegetation of an area can lead to loss of complex species through migration or starvation due to fewer resources. These ecosystems would have to undergo succession to recover the more complex species.

How does an ecosystem change during succession?

During succession, an ecosystem starts as nearly uninhabitable and is transformed by the progressively more complex organisms that move back into the area. Succession occurs in nearly barren areas, such as on land newly created by a volcano or in burned areas following a fire

Which is faster primary or secondary succession?

Secondary succession is usually faster than primary succession because soil and nutrients are already present due to ‘normalization’ by previous pioneer species, and because roots, seeds and other biotic organisms may still be present within the substrate.
