Answer:
As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity. However, at sufficiently high levels of light intensity, the rate oxygen evolution remains constant.
The hormone ethylene is a gas and disperses easily.
Answer:
Competition between two species happens when both species are using the same resources in an area. This usually happens when a new species moves into the area of the current species. Competition leads to both species being harmed.
