प्रश्न
Imagine all the seeds produced by a plant happen to fall under the same plant and sprout into new plants. Mention any two problems that will be faced by the new plants.
उत्तर
If all the seeds produced by a plant happen to fall under the same plant and sprout into new plants, then in this situation plants will face the following problems:
- The new plants will compete for sunlight, water, nutrients, and space. Limited availability of these essential resources can lead to poor growth and reduced survival rates.
- The close proximity of the new plants will cause overcrowding, limiting their ability to spread out and grow properly. This can result in stunted growth and increased susceptibility to diseases and pests.
- A large number of plants will grow in a small, limited space. The water and the minerals available to them in the soil will be limited.
- The air surrounding them will not be enough and less sunshine will be available to them. As a result, most of these sprouted plants will die.
- Soil nutrients will be rapidly depleted as many plants try to absorb the same nutrients, leading to nutrient shortages.
- The plants will struggle to get adequate water, especially in dry conditions, affecting their overall health and survival.
