Villi occur in the digestive system, helping to move food through your system and absorbing nutrients.
1. Respiration-process by which plants release CO, while they break down the sugar
2. Animals eat plants- They break down sugars and starches by a process of metabolism and the products are energy water, and CO2 molecules.
3. Decomposition-when plants die, their parts (wood, leaves) decay bringing the carbon into the ground
4. Root respiration- respiration that occurs in roots, adds to soil respiration (the amount of CO2 produced through root respiration is determined by the root biomass ).
<h3><u>Answer;</u></h3>
D) India was a separate continent until forty-five million years ago.
<h3><u>Explanation</u>;</h3>
- <em><u>Continental drift serves as one of the evidence of evolution. Different kinds of animals and plants live in different parts of the world. This is true now, and it was true in the past. </u></em>
- Therefore, when a fossils of the same animal or plant is found on different continents, then that is evidence that those two continents may have been a single continent when those fossils were formed.
- Fossils show that the continents drifted because similar fossils were found where the continents were together millions of years ago.
Photosynthesis is using Light Energy to convert CO2 and water into oxygen and carbohydrates such as sugar or starch.
Cellular respiration is using oxygen to convert biochemical energy into ATP (Energy) and CO2
The relationship between the 2 is that what the 2 creates and let out is what the other needs to work like photosynthesis creates oxygen as a byproduct and to do cellular respiration, it needs oxygen. Cellular respiration creates CO2 as a byproduct and to do photosynthesis, it needs CO2.
