Answer: all of the above except ectothermy and thin leaves. Photosynthesis, broad tap root, endotherm and production of antifreeze proteins are adaptation of the organism found in rainforest biomes.
Step-by-step explanation:
Rainforest presents challenges to the organisms living in it. In order to live in the rainforest, the organisms has to develop several adaptation features.
Such features include;
Photosynthesis: all plants photosynthesize by making use of carbon dioxide in order to produce oxygen and sugar.
Broad tap root: since the soil is moist, plants need a broad tap root for proper anchorage.
Endotherm: endotherm animals make use of inner heat, since most time there is cold. Endotherm animals are called warm blooded animals
