Sustainability What is biodiversity? Biodiversity refers to the variety of biotic life in an ecosystem or habitat Biodiversity in Ecosystems? How did you make your ecosystem model biodiverse? Did you include only on species of animal or multiple? Why do you think it is important for an ecosystem to have a diverse group of plant and animal species? What is sustainability? • Sustainability involves conserving ecological balance. • It aims to prevent depletion of natural resources. • Ecological balance is crucial for supporting diverse plant and animal species in an ecosystem. What is biodiversity? • Biodiversity refers to life's variety and variability on Earth. • Ecosystems require a mix of species to flourish and regenerate. • Animals and plants depend on the environment for shelter, safety, and nutrients. • Limited plant species would impact nutrient access for many animals. Ecosystems and Matter Cycling • Ecosystems are delicate, with crucial connections among producers, consumers, and decomposers. • Matter cycles within ecosystems, contributing to their functioning. Example #1: Bears & Salmon • In forest ecosystems, bears transport salmon from rivers into the forest. • Bears consume parts of the salmon and leave leftovers to decompose. • Decomposers break down the remaining salmon, enriching the soil with nutrients. • Nutrients from decomposition support plant growth as plants absorb them through their roots. Example #2: Crop Rotation • Farmers rotate crops seasonally, enhancing soil fertility. • Decomposition of waste from previous crops generates nutrients for future crops. So what? • Sustainability and biodiversity are vital for maintaining a healthy ecosystem. • Connections among producers, consumers, and decomposers support the ecosystem's needs. • Each role in the ecosystem is crucial; removing plants would disrupt food sources for consumers. • Consumer actions generate waste, consumed by decomposers, returning nutrients to the soil for plant growth. • Interruptions in this cycle can harm ecosystems, highlighting the importance of sustainability.
