Question
Explain the Term :
Double circulation

Answer

Double circulation: Double circulation in the heart refers to the way blood flows through the heart and the rest of the body in two separate loops or circuits. This system is composed of:
Pulmonary Circulation: Deoxygenated blood is sent from the heart to the lungs to get oxygenated, then returns to the heart. Systemic Circulation: Oxygenated blood from the heart is circulated throughout the body to deliver oxygen, then deoxygenated blood returns to the heart.
This efficient system enables high blood pressure in organs and quick oxygen delivery, vital for high metabolism in mammals and birds.

Given below is the diagram showing aquariums with light and without light. Read the information and fill in the blanks:

Image
A group of students conducted an experiment to understand the significance of photosynthesis in the ecosystem. They observed two aquariums, one with aquatic plants and the other without any plants, both exposed to light. Over time, they noticed that the aquarium with plants had clearer water, while the other became turbid. This experiment highlighted the role of photosynthesis in oxygen production and nutrient cycling, essential for maintaining aquatic ecosystems.
The presence of plants in the aquarium helped in (i) __________ the water by absorbing carbon dioxide. The unclear water in the aquarium without plants was due to the (ii) __________ of oxygen and the accumulation of waste. Photosynthesis is crucial for (iii) __________ as it produces oxygen and removes carbon dioxide. In the absence of photosynthesis, aquatic ecosystems would suffer from
(iv) __________ imbalance and poor water quality. The experiment demonstrated the importance of (v) __________ maintaining aquatic environments.
