Science Week 5 Test .2

• Are abiotic factors important and why or why not?

  Yes, abiotic factors are important because they influence the physical and chemical environment of an ecosystem, affecting the organisms living within it.
• Why are polliantors important?

  A pollinator is an organism such as a bee, bird or bat that moves pollen from the male reproductive organs (anthers) of a flower to the female reproductive organs (stigma) which then allows for the fertilisation process to begin. Symbiotic relationships and the contribution of pollinators show how everything in nature is connected, emphasizing why its so crucial to protect biodiversity through conservation efforts.
• Why are pollinators so important again?

  Pollinators are important for maintaining biodiversity within ecosystems by facilitating the reproduction of a wide variety of plant species. Pollinators are also essential for food production because many crops, such as fruits and vegetables, rely on pollinators for their reproduction which ensure food sources for both humans and animals. Pollinators also contribute to the ecosystems stability by supporting the reproduction of plants which form the beginning of food webs, helping keep balance to the ecosystem and ensure it works constantly.
• 4 detailed examples of pollinators?

  Bees, butterflies, hummingbirds, bats
• Detailed example of a mutualistic relationship?

  The bee and the flower. Bees fly from flower to flower gathering nectar, which they make into food, benefiting the bees. When they land in a flower, the bees get some pollen on their hairy bodies, and when they land in the next flower, some of the pollen from the first one rubs off, pollinating the plant. This benefits the plants. In this mutualistic relationship, the bees get to eat, and the flowering plants get to reproduce.
• Detailed example of a commensalism relationship?

  Remora fish have a disk on their heads that makes them able to attach to larger animals, such as sharks, mantas, and whales. When the larger animal feeds, the remora detaches itself to eat the extra food.
• Detailed example of a parasitic relationship part 1 ?

  Barnacles are the parasites, crabs are the host. Barnacles are crustaceans that live in seawater.

  How does the relationship between barnacles and crabs work? Barnacle larvae grow up within the female crab, living where the crab's eggs normally should be. The female crab thus can't have crab babies and instead hatches more barnacle larva.
• How do abiotic and biotic factors influence each other in the ecosystem P1?

  In any ecosystem, the balance of life relies between abiotic (nonliving) and biotic (living) elements. Biotic factors, including plants, animals, fungi and bacteria, rely on abiotic components for survival. These abiotic factors, ex. air, soil, water, light and temperature shape the distribution, behavior, health of living organisms.
• How do abiotic and biotic factors influence each other in the ecosystem P2?

  Nutrient availability, temperature, water access, and other abiotic conditions directly impact the growth, reproduction, and interactions of biotic communities. The activities of living organisms, such as nutrient cycling, decomposition, and predation, influence abiotic factors. This connection between the living and nonliving components sustains the ecosystem balance
