Species Diversity Pollution Measuring Stability Ecosystem Explain Obtain

This card explains the importance of measuring species diversity: higher diversity often indicates a more stable ecosystem, and pollution leads to lower diversity.

Bu kart, tür çeşitliliğini ölçmenin önemini açıklar: daha yüksek çeşitlilik genellikle daha kararlı bir ekosistem anlamına gelir ve kirlilik daha düşük çeşitliliğe yol açar.

Front Explain why measuring species diversity allows us to obtain info about the stability of an ecosystem or the degree of pollution in an ecosystem.
Back Importance of measuring species diversity:
  • Diversity is often proportional to stability of ecosystem - most stable have evenly distributed species in good sized pops
  • Pollution causes harsh conditions where few species dominate so high pollution - low diversity
