Trawling refers to the process of fishing that uses a fishing net through the sea water behind one or more boats. It is a common method of extraction of sea living resources.
It is the main cause of the degradation of the seabed which threatens the biodiversity. It kills a number of corals, sponges, fishes and the microflora on the seabed. Corals, particularly are damaged wouding the tissue and making them susceptible to infection. It also removes certain economically important sea weeds. The ocean sediments are disturbed causing the suspended solids to enter the seawater and causing turbidity affecting the penetration of sunlight. The suspended soilds can also cause growth of harmful algae causing algal blooms affecting the other biotic factors of the sea. The disturbance in the ocean sediments due to trawling causes the harmful pollutants like DDT that are trapped in the sediments reach the water column and enter the food chain of the living organisms.
Answer:
The correct answer is option A, when there are unlimited resources
Explanation:
In an exponential growth, the size of population increases with a tremendous rate as there is no competition for resources among the species. A common example of exponential growth can be of bacteria, whose population increases tremendously in unlimited supply of nutrients. The exponential growth can be mathematically represented as
dN/dT=rmaxN
where r max = maximal growth rate for a species
N = population of a species
<h3>Adverse effects of covering the land with concrete and asphalt is Natural resources are depleted.</h3>
- Asphalt is a petroleum-based product. Concrete requires rock, sand and a fabricated cement component to strengthen the material hold the pavement material.
- Fortunately, industry innovation has led to meaningful progress toward resource conservation.
- Road construction companies have developed ways to reuse existing concrete and asphalt by remixing it materials.

Explanation:
When two tectonic plates slide past each other, the place where they meet is a transform or lateral fault. The San Andreas Fault is one of the best examples of lateral plate motion
All of the listed have the same amount of nutrients unless dried or affected in some other way not said.
