How many plant and animal species do wildlife experts estimate are endangered?
a.
less than one million
b.
1 to 3 million
c.
3 to 10 million
d.
10 to 30 million
i know for a fact its not b

The right answer is c. 3 to 10 million

The latest estimates are a bit more precise: there are 8.7 million living species (which is included in the range between 3 and 10 million), 6.5 million on land and 2.2 million in the water. Which is amazing, since there is more sea than land on our planet.

Researchers estimate that there are 7.77 million animal species, only 298,000 plant species and 611,000 species of fungi and molds.

The answer is a: less than one million.

Explanation:

Endangered species are species of plants and animals that are at risks of extinction either due to natural or anthropological process. The International Union of Conservation of Nature (IUCN) is the body that has been working on assessing different taxonomic groups for threats and species found to be at risk are published in the red list of threatened species.

As at 2019, over 105,000 species have been assessed for threats out of which more than 28,000 species were identified to to be at risk of going into extinction. That is about 27% of the total number of assessed species.

28,000 is still less than a million. The correct option is a

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

i'll try what topic lol
