Why is it good for an annual plant to be indehiscent and not have a long distance dispersal system?

Final answer:

An annual plant may benefit from being indehiscent and having limited seed dispersal to ensure seeds fall in suitable conditions, make use of seed dormancy, and to conserve resources for seed production and survival.

Step-by-step explanation:

It may be beneficial for an annual plant to be indehiscent (not open to release the seeds when ripe) and not have a long distance dispersal system because such a plant strategy can ensure that seeds fall in an environment that is already proven to support the parent plant. Indehiscent fruits may rely on seed dormancy which allows the plant to buffer against variable conditions by dispersing seeds through time until conditions are right for germination. This can be particularly important in habitats where the chances of successful germination and seedling establishment are increased closer to the parent plant, such as in areas with high predation pressures or where the correct soil type or microclimate is restricted to a particular location. Furthermore, since annual plants only live for one year, investing in long-distance dispersal could mean fewer resources for seed production and survival, potentially reducing the overall fitness of the plant.
