Faahfaahinta casharka

Natiijada casharka

I can describe and choose suitable methods to sample populations of plants or animals.

Muuji qoraalka
Sampling is used to obtain estimates of populations within an area because it would be impossible to count them all. There are lots of different sampling methods that can be used to sample plants and animals. Sampling is essential for conservation to monitor populations and compare them.

    • 2
    • Jawaabta saxda ah:20
    • 40
