About 54% because of economic growth in food production has increased by a large margin because the world population is ever growing
Photosynthesis is measured by the amount of oxygen produced. Counting pondweed bubbles or using the Audus apparatus to determine the amount of gas evolved over time can both be used to quantify oxygen.
<h3>
What is photosynthesis?</h3>
Photosynthesis is the conversion of light energy into chemical energy by green plants and other organisms. Light energy is collected and utilised by green plants during photosynthesis to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.
The forming bubbles are either counted or recorded using light barriers, which is difficult due to their small size and frequently changing ascent velocity. When gas bubbles produced during photosynthesis by aquatic plants leave the plants, they produce different sound pulses.
B. Because the gas collected contains water vapor in addition to oxygen, it is not pure oxygen.

Answer:
In an eco-system, all animals and insects are important. Since there is no picture, I'll descibe what would happen. If a keystone species went missing or extinct, shortly after the rest of the ecosystem will callapse. The bird population would decrease because lack of food, shelter or environment, then those who feed on birds will slowly decline, then worms or insects that the bird was keeping in check, overpopulate. This can have disaterous consequences, not only for this specific ecosystem but for any.
Answer:
spiders
Explanation:
While humans and many other species have red blood, due to the iron in their hemoglobin, other animals have different colored blood. Spiders(as well as horseshoe crabs and certain other arthropods) have blue blood due to the presence of copper-based hemocyanin in their blood. Some animals, such as the sea cucumbers, even have yellow blood.
Let say, polled (without horn) parent cattle is dominant (PP) and parent horned cattle is recessive (pp). They cross bred which produced all polled calf F1 generation. F1 will be hybrid for trait horn (Pp). On Selfing of F1 progeny ( Pp x Pp) will give 1 homozygous polled (PP) cattle, 2 heterozygous polled (Pp) cattle and 1 cattle with horn recessive (pp) in F2 generation.
