Q:

What are pioneer species?

A:

Quick Answer

Pioneer species are species which recolonize an area after there has been damage or disruption to the ecosystem. These types of plants are normally hardy plants that need very little to survive, such as lichen or plants with very long roots that give them better access to nutrients.

Full Answer

Pioneer plants also have seeds that can lay dormant for long periods of time, waiting on conditions to improve before growing. Weeds are a common pioneering plant and can grow rapidly to fill the damaged area. These pioneer plants will often die and create plant litter that helps increase the nutrients available for plants that will grow during the secondary succession.

    What is the role of fungi in the ecosystem?

    A:

    Fungi are vital decomposers in the ecosystem, breaking down dead organisms and biological waste, freeing nutrients for use by other organisms and clearing away their remains. Fungi also act in partnership with some plants and algae, and are often vital to the survival of these organisms. Some species are parasites.

  • Q:

    What are some of the abiotic factors in a chaparral ecosystem?

    A:

    Some of the abiotic, or non-living, factors affecting the ecosystem in a chaparral are temperature, wet winters with dry summers, a nearby body of water and wildfires. In a chaparral, which is also known as a Mediterranean climate, warm air rising from the equator combines with an adjacent body of water to provide a high degree of rain during a relatively warm winter which stands in contrast to a hot and dry summer. Chaparral biomes across the world are most frequently found at latitudes between 30 and 40 degrees north and south of the equator and contain characteristically predominant shrubland plant communities.

  • Q:

    What is the seed germination process?

    A:

    The seed germination process is a complex process in which the embryonic plant created by sexual reproduction of plants propagates the species by forming a new, independent plant. In order to germinate, the moisture and temperatures must be right. New plants live a short while on the sugars stored in the seed, requiring the plant to start gathering nutrients and moisture from the soil and producing its own food quickly.
