what important law was passed in 1973 to protect organisms with low population numbers? 1 point biodiversity conservation act wildlife protection act clean water act endangered species act saving animals from extinction act animal welfare act what three levels on the iucn red list are considered to be threatened? 1 point vulnerable extinct least concern critically endangered extinct in the wild near threatened endangered

Explanation:

• First Question: The Endangered Species Act (ESA) was passed in 1973. Its main goal is to protect species that are at risk of extinction (organisms with low population numbers). The Biodiversity Conservation Act is not a commonly - known major U.S. act from 1973 for this specific purpose. The Wildlife Protection Act is a more general - term, and in the U.S. context, the ESA is the key act. The Clean Water Act focuses on water quality. The Saving Animals from Extinction Act is not a standard name for the 1973 act. The Animal Welfare Act is more about the treatment of animals in general, not specifically about protecting species with low populations.
• Second Question: According to the IUCN Red List, the "threatened" categories are Vulnerable (facing a high risk of extinction in the wild in the medium - term future), Endangered (facing a very high risk of extinction in the wild in the near future), and Critically Endangered (facing an extremely high risk of extinction in the wild in the immediate future). Extinct means the species no longer exists. Least Concern means the species is not at risk. Extinct in the Wild means the species only exists in captivity. Near Threatened means the species is close to qualifying for a threatened category but is not yet there.

Answer:

• First Question: Endangered Species Act
• Second Question: Vulnerable, Critically endangered, Endangered
