Plants Competition

1. Plants need water, carbon dioxide(from air) and sunlight to make 
    food.
2. Plants also need nutrient from healthy growth.
3. Plants get water and nutrient from the soil.
4. If there are too many plants growing in the same place, the place 
    will be overcroeded and the resources become limited.
5. The plants will compete to get enough sunlight, water, nutrient 
    and space.
    a) For example, when there are too many seedlings planted in a 
        pot, they will compete to get enough space, water, sunlight and 
        nutrient to grow. 
    b) This will result in unhealthy growth.

6. Plants in the rainforest have different heights because they 
    receive different amounts of sunlight, space, water and nutrient.
7. The plants face strong competition to get sunlight, space, water 
    and nutrient.

Competition for sunlight, water, nutrient and space has
resulted in trees of different heights         

8. In a competition, plants which are stronger will win. The plants 
    will grow better and healthier. Weaker plants will have stunted 
    growth, wilted and eventually die.
