Calculate the Simpsons biodiversity index of the community below correct to one decimal place (use pen and paper to draw a table)

Sea holly: 2

Sand Couch: 8

Sea bindweed: 1

Sporobolus pungens: 1

Echinophora spinosa: 3

Total: 15

A population is

• a group of similar species in different areas

• a group of the same species in the same geographic area.

• a group of several species in the same geographic area

• a group of several species along with their abiotic factors in a small area.
