They can be found in elevations from sea level to 5,000 m (16,000 ft). They prefer warmer, tropical climates but are adaptable and can live in all but the most extreme environments. Lizards also exploit a number of habitats; most primarily live on the ground, but others may live in rocks, on trees, underground and even in water.
Trees cannot grow at high altitude, because of cold temperature or lack of available moisture. [82]: 51 The lack of trees causes an ecotone, or boundary, that is obvious to observers. This boundary is known as the tree line. The highest-altitude plant species is a moss that grows at 6,480 m (21,260 ft) on Mount Everest. [83]
A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes).

The biodiversity of plant species is the highest on Earth with one 2001 study finding a quarter square kilometer (62 acres) of Ecuadorian rainforest supports more than 1,100 tree species. [54] A study in 1999 found one square kilometer (247 acres) of Amazon rainforest can contain about 90,790 tonnes of living plants.
Recent figures indicate that there are more than 1.4 billion insects for each human on the planet, [27] or roughly 10 19 (10 quintillion) individual living insects on the earth at any given time. [28] An article in The New York Times claimed that the world holds 300 pounds of insects for every pound of humans. [28]
Most reptiles are also cold-blooded, so they’re unable to regulate their own body temperature. ... plants and small animals. With a lifespan of 20 years or more, you’ll have a friend for ...
Small bushes are also found, along with a small number of freshwater plants. The plant species vary with different factors such as the fertility of the soil, the humidity, and altitude. There is a lack of data about many species in the islands, as well as a lack of long-term data about the environment.
Mammals or reptiles might have floated on a piece of wood and drifted to the islands. Some animals like marine iguanas, may have swum there. Some animals like marine iguanas, may have swum there. In most environments the larger mammals are the predators at the top of the food chain, but those animals did not make it to the Galápagos.
