Ecological community-2023-1

When several populations are inhabiting a certain space, they form a community.

• true

• false

The elements that constitute the ecological community depend on each other.

An example of this can be seen in a forest, where the population of eagles depends on the population of snakes on which they feed, and these depend on the population of rodents, which in turn depends on the population of grasses from which they feed.

• true

• false

Ecological community is made up two elements: Biocenosis and Biotope

• False

• True

The following element combines physical and chemical factors in a territory and that are suitable for the growth of a community

• diversity

• biocenosis

• biotope

• abundance

It refers to the total number of species that form a community.

• stratification

• dominance

• abundance

• horizontal stratification

When there is great diversity within a community, food chains are longer and more complex, greater types of inter-population relationships and greater ecological stability.

• false

• true

It is the number of individuals per species settled in a community. It is a quantifiable density-related characteristic that is associated with stability.

• stratificacion

• dominance

• diversity

• abundance

When a species predominates in a certain extension of land due to its abundance, it is said that this species is dominant.

• stratification

• abundance

• variety

• dominance

The different populations that make up a community are distributed occupying all the possible spaces of an entire territory due to their characteristics

• dominance

• stratification

• diversity

• abundance

When considering the vertical axis of a community (such as the height of the vegetation from the ground, or the depth of a body of water from its surface to the bottom).

Imaginary lines can be established at different heights, layers, or growth strata. In addition, we can distinguish the distribution of the animals that inhabit it.

- Arboreal (highest)

- Shrub

- Herbaceous

- Grass (lowest)

• Horizontal stratification

• Vertical stratification
