Answer 1

Step-by-step explanation:

Living organisms exist almost everywhere from mountain peaks to the ocean depths; from deserts to the rainforests. We must make every effort to preserve, conserve and manage biodiversity. Protected areas, from large wilderness reserves to small sites for particular species, and reserves for controlled uses. The wildlife sanctuary, biosphere reserves and national park are designated places for protecting the wild plants, animals and natural habitats.

Answer 2

Answer:

yes

Step-by-step explanation:

1. a+(b+c) =(a+b)+c.

15+(-9+(-12)) = (15+(-9))+(-12). 15-21=6-12

-6= -6
