Question
The by-product of the photosynthesis process is __________
- Carbon-dioxide
- Oxygen
- Glucose
- Both Oxygen and Glucose
Hint:
- Photosynthesis is an anabolic process in which plants use carbondioxide, water and to make food for themselves in the presence of sunlight
- Chlorophyll absorbs light energy which is converted into chemical energy of food that is glucose
- Oxygen released by plants is the byproduct of photosynthesis which is liberated due to oxidation of water.
The correct answer is: Both Oxygen and Glucose
Oxygen is the byproduct of photosynthesis

Pick the odd one out.
- Ecotones could be narrow (between a grassland and a forest) or wide (between forest and desert)
- Ecotones are the zone of tension
- As we move away from a community or ecosystem, the quantity and population density of the species within that community typically decreases
- Some organisms in a well-developed ecotone are similar to those in nearby communities
