1. Floods can devastate an ecosystem, however they can also have a positive impact. Please explain the positive impacts major floods can have on the ecosystem. 2. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
3.Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems. (Not from google )

1. Whilst flood events are devastating to humans they are a natural occurrence that can provide negative and positive important environmental impacts.

Flooding helps spread organic material, nutrients, and sediments which enrich floodplain soils. They also replenish water resources and trigger life processes such as bird breeding events, migration, and seed dispersal in flora and fauna adapted to these cycles, while good soil moisture can allow crops and pastures to be established.
