Nutrients are circulated throughout the biosphere because of biochemical cycling.
Answer: Option C
<u>Explanation:</u>
Apart from vitality, water and a few other chemical components spin through biological systems and impact the rates at which life forms develop and duplicate. Around 10 noteworthy supplements and six minor nutrients are basic to all creatures and plants, while others assume significant jobs for chosen species.
The most significant biochemical cycles influencing environment well being of the water, carbon, nitrogen, and phosphorus cycles. Thus it is due to biochemical cycling, nutrients are circulated through out the biosphere.
Blood vessels visible in the posterior view of the heart include the Superior and inferior vena cava and the pulmonary veins. The superior vena cava and the inferior vena cava drain systemic venous blood into the posterior wall of the right atrium. The pulmonary veins transport blood from the lungs back to the heart and are best seen in posterior view of the heart. Other features visible in the posterior view include, right and left atrium, right and left ventricle, aorta, aortic arch, pulmonary veins and arteries, coronary sinus, coronary artery and posterior interventricular artery.
The reason is to help in seed dispersal. Seed dispersal is the movement or transport of seeds away from the parent plant. Due to the fact that plants have very limited mobility they have to rely upon variety of dispersal; vectors to transport their seeds, including both abiotic and biotic factors. Seed dispersal is important because if seed are not dispersed, many germinating seedlings will grow very close to the parent plant which would result to competition between every one of the seedlings as well as the parent. The competition for essential growth factors such as light, space, water and nutrients.
Levels of organization in ecosystem:
1.Individuals or organisms
<span>2.Population- A group of organisms of a given species that live in a specific area at a given time</span>
<span>3.Comunity- All of the populations of different species that live in the same area and interact with one another</span>
<span>4. Ecosystem- Community (biotic) interacting with the environment (abiotic)</span> <span>5.Biome- A group of ecosystems sharing similar characteristics</span>
<span>6. <span>Biosphere-The sum of all the ecosystems established on planet Earth.</span></span>
