Predict how an unusually prolonged drought might affect a biological community

1 answer:

6 0

Primary consumers (such as grazers and browsers) of the biological community will put pressure on the primary producers (these are plants) since the primary producers have limited resources (water) to reproduce due to the drought. The primary producers hence become scarce and cause the primary consumers to compete for limited resources. This causes the primary producers to reduce in population. Reduction in their population causes limited resources for secondary consumers and this cascades up the food web to tertiary consumers.

Climax community- most stable community that takes hundreds of years to develop. The types of organisms change due to __?__.

Svetlanka [38]

Answer:

competition

Explanation:

An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Its structure, composition and distribution are determined by environmental factors such as soil type, position in the landscape, altitude, climate and water availability(Department of Agriculture).

A climax community refers to the last stage of ecological succession in which the community remains relatively unchanged unless it is destroyed by events such as fire or human interference.

Competition between species in the same habitat is an important biotic factor in discussing ecological succession and the emergence of climax communities. Competition leads to a drop in the diversity of species in a given ecosystem because the dominant species live on and reproduce while the other species die off.

Non-protein coding DNA in eukaryotes contains repetitive elements that include (select all that apply): Group of answer choices

Olegator [25]

Answer:

interspersed, transposon-derived repeats, simple sequence repeats.

Explanation:

In the human genome, not only the protein coding genes are present, in fact these genes make up just a very little portion of the human genome about 1.5-2% of the entire human genome. Repeats make up about 48% of the human genome which is the largest and the rest include, conserved non coding sequences (43.5%), heterochromatin regions etc.

Some of the repetitive elements includes LINEs, SINEs, DNA fossils tranposoon, Retrovirus like elements. all these are transposable elements which are mobile DNA sequences that can migrate to different regions/areas of the genome.

Microsatellites (simple sequence repeats) are tracts of repetitive DNA in which certain DNA motifs are repeated normally 5-50 times.

All of the cacti is removed from a desert ecosystem, what would happen to the population of cactus dwelling birds and in turn th

pishuonlain [190]

The population of cactus dwelling birds will decrease and that of the animal they eat will increase.

Explanation:

When cacti is removed from the desert ecosystem, the birds that have their nest on the cacti will no longer have a home so they will migrate to other areas with favorable ecosystem.This will reduce the number of birds in this ecosystem.In turn, the animals that were feed by the birds will have the chance to multiply in numbers because a predator has been removed in the ecosystem.
