Which of the following statements is true about nitrogen fixation?

a. It is done only by plants.
b. It is done mostly by bacteria.
c. It is how animals make proteins.
d. It is a form of decomposition.

Answers

Answer 1

Explanation:

option B is the correct one as it is done by nitrogen fixing bacteria.

Answer 2

It is absorbed by bacteria from the atmosphere as a gas and released to the soil, mostly as ammonia. Thus, option B is correct.

What is role of bacteria in nitrogen fixation?

The purpose of nitrogen-fixing bacteria is to provide plants with a crucial nutrient that they are unable to receive naturally from the air. Microorganisms that fix nitrogen can obtain assimilate N for plants in a way that crops cannot.

More than 90% of all nitrogen is fixed by nitrogen-fixing bacteria, which makes them crucial players in the nitrogen cycle.

The majority of nitrogen fixation is done spontaneously by bacteria in the soil. In the soil, nitrogen is fixed and changed in form.

Some bacteria form symbiotic relationships with plant roots that are advantageous to both the plant and the bacteria.

Therefore,  It is done mostly by bacteria.

When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population.

Answers

Answer:

The correct answer is - biodiversity is a good thing.

Explanation:

Biodiversity is the variety of types of life including all organisms present on earth or if related to a specific area then the ecosystem. Biodiversity helps in boosting the productivity of the ecosystem and each organism of the ecosystem plays an essential role in it.

The higher the biodiversity more chances of survival of organisms. Biodiversity provides oxygen, water and soil that helps to strengthen the ecosystem.

Answers

Answer:

The process of a plant converting sunlight, carbon dioxide and water into food

Explanation:

Hey there!

Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

If you can, visit a ranch! It would be best if you can create this project from what you experience on a ranch. If that is not possible, you can do your research on the Web.

If you are on or near a ranch, get permission to visit and spend time on the land, asking questions of the rancher(s) who run it. Some questions you will want to ask include:

What is the location and size of the ranch?
What kinds of ranch animals are there?
What kinds of wildlife are there?
How/where do they interact (water supplies, pastures, woods)?
What are the benefits to the land and water of the animals interacting?
How do the animals get along?
What predator problems do the ranchers face?
How do they protect from predators?
What fencing issues with wildlife are there?
What are the migration patterns of the animals?
What other things do the ranchers do with regard to wildlife management?
The finished product can be a written report (should be at least three pages, double-spaced, and include photos), or a presentation or video (make it at least four minutes long). If you can, take photos or videos (with permission).

If you are not near a ranch, do your research through videos and articles on the Web. Be sure to fully cite all your sources, and be sure that you have permission to use the information, photos, or videos. If you have personal experience with wildlife on ranchlands, add it to your report or presentation. Make it interesting, visual, and focused on how ranches and wildlife benefit each other, and include details of best-management practices that you encounter.

Answer:

The feasibility and profitability of game ranching have been amply demonstrated by a number of studies. The rationale behind advocating game ranching in Africa is that conditions in many parts of' the continent, whether resulting from inadequate rainfall or presence of certain disease organisms' are not appropriate for production of exotic cattle and other domestic stocks. Indigenous wild animal species on the other hand have evolved in the African ecosystem and are better adapted to the prevailing conditions and should therefore be more productive.

Game ranching is currently most developed in southern Africa (particularly South Africa Namibia and Zimbabwe), although a private game ranch, the Galana Ranch, was established in Kenya in the 1970s (King and Heath, 1975; Thresher, 1980). The ranch initially focused on three species: the fringe eared oryx, Oryx beisa callotis, the African buffalo and the eland. Reported advantages of the eland over the Boran cattle included much lower water requirement, faster breeding and growth, earlier maturity and ability to put on weight in grazing conditions under which the Boran cattle began to lose weight and approximately 14 % higher dressing out weight. In addition to these biological and physiological advantages a cost-benefit analysis of maintaining a breeding herd of 11,000 oryx and 5000 Boran on the ranch showed clearly that the financial returns on the oryx was far superior to that of cattle (Thresher, 1980).

Explanation:

I am not interested

Numerous studies have amply shown that game ranching is both feasible and profitable.

What is Argument?

The argument in favor of game ranching in Africa is that the climate in many regions of the continent, whether as a result of insufficient rainfall or the presence of specific disease organisms, is insufficient for the breeding of exotic cattle and other domestic species.

On the other hand, native wild animal species have evolved in the African ecosystem and are better adapted to the current conditions; as a result, they should be more productive.

Although a private game ranch, the Galana Ranch, was founded in Kenya in the 1970s (King and Heath, 1975; Thresher, 1980), southern Africa, particularly South Africa, Namibia, and Zimbabwe, currently has the most developed game ranching industry.

Therefore, Numerous studies have amply shown that game ranching is both feasible and profitable.
