An echinoderm uses its tube feet for attachment and feeding.
Explanation:
- Tube feets are usually considered as locomotory organ of Echinoderm.
- They have tube feets arranged around their oral groove.
- These tube feed help the organism to push the food into the oral groove.
- Tube feets also help the echinoderms to attach themselves to the floor of the ocean and locomote slowly in a sliding manner.
The statement is true. Dead zones are the zones of oxygen depletion, which is caused by excessive running off of the fertilizers into the water body. These chemicals, particularly the nitrates, which are used by algae etc. which bloom by using the nitrates and use the oxygen present in the water. When they die, oxygen levels become critically low till then, for other aquatic animals like fishes etc., to survive.
1. The best answer is Stomata takes in carbon dioxide and release oxygen. Photosynthesis is the process that take place in the leafs of green plants where chlorophyll absorbs sunlight and converts the energy from the sunlight to chemical energy. The process produces simple sugars and oxygen, oxygen is either released to the atmosphere or used in cellular respiration. Simple sugars (glucose) are stored as glycogen and used as an energy reserve.
2. The statement is true. Water and carbon dioxide are are raw materials of photosynthesis. Water is broken down in the first stage of photosynthesis using sunlight to produce oxygen and hydrogen ions. The second stage of photosynthesis involves carbon dioxide fixation producing simple sugars
(glucose).
3. The equation that supports the conservation of energy is;
6CO2 + 6H2O + light = C6H12O6 + 6O2
This is the process of photosynthesis that involves use of carbon dioxide and water to produce glucose and oxygen.
Six carbon atoms are used to generate another six carbons in glucose, hydrogen atoms and oxygen atoms taken in remain the same in the products.
