Match each term to its description.

stepladder [879]

Based on ecological studies, the definitions below applies to the given terms:

Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

<h3>What is ecology and what are some terms in ecology?</h3>

Ecology is the study of living things and their interactions with their environment.

Some terms in ecology include:

Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

Compound A serves as a prodrug for the analgesic benzocaine. (A prodrug is a pharmacologically inactive compound that is convert

NemiM [27]

Answer:

The hydrolysis in aqueous HCl of compound A can lead to the formation of a carboxylic acid and an alcohol.

Explanation:

The picture shows the structures of compound A, benzoncaine and the possible products of the proposed reaction.

The acidic hydrolysis is the inverse of the esterification reaction. Therefore, the ester group of compund A will react to form the equivalent carboxylic acid and alcohol.

In order to form benzocaine, the hydrolysis happens in with the nitrile group.

What is the condition of water in the hydrosphere right now?

SCORPION-xisa [38]

Answer:

A planet's hydrosphere can be liquid, vapor, or ice. On Earth, in the places at the north and south pole, water exists in ice or glacier form, in the atmosphere it exists in vapor form and liquid water exists on the surface in the form of oceans, lakes and rivers. It also exists below ground as groundwater, in wells and aquifers. Water collects in clouds, then falls to Earth in the form of rain or snow,

What are the effects on the bodies of water? use terms algal bloom, dead zone and hypotoxic

Anna35 [415]

Water pollution is defined as the mixing of water with unwanted substances and that makes water unsafe.

Water pollution includes runoff of excess fertilizers,

herbicides, and insecticides from agricultural lands

and residential areas; oil, grease, and toxic chemicals

from urban runoff and energy production; and

sediment from improperly managed construction sites,

crop and forest lands, and eroding stream banks.

Polluted waters have high BOD which affects aquatic biodiversity.

Hpotoxic substances such as lead, arsenic, and fluoride cause many problems to aquatic animals and humans. Water contaminated with Arsenic results in diseases such as arsenicosis. Fluoride had been reported to cause depression in DNA and RNA synthesis in cultured cells, significant reductions in DNA and RNA levels, and conditions including aging, cancer, and arteriosclerosis are associated with DNA damage and its disrepair. Lead causes problems related to the central nervous system. Children and pregnant women are most at risk. Routine applications of fertilizers and pesticides for agriculture and uncontrolled runoff in water bodies. Adds nitrogen and phosphorus to water. It adds nitrogen and phosphorus to water causing eutrophication and algal blooms.

Therefore, all these activities make our water bodies a death zone for the marine ecosystem as well as humans.
