Answer:
True.
Explanation:
Extinction vortex is a model used by scientists to understand extinction dynamics within a community. This model allows scientists to assess and understand how a population can become highly vulnerable to elements of its habitat, becoming increasingly apt for extinction. According to this model, any organism is capable of extinction, as all are susceptible to having a gene pool that will not allow its survival, regardless of the environment.
The correct answer is: 4) Standing defenses are always present; induced defenses develop in response to a threat

Explanation:
Tropical rain forest are one of the important biomes of the world that is characterized by a short or no dry season and a precipitation of overall 60 mm each month. They are also known as lowland equatorial evergreen rainforest. If we talk about location, they mostly are found between fall between the Tropic of Cancer and the Capricorn since they lie near to equator and they receive sufficient amount of sunshine and rain.
Due to their location near the equators, they receive greater amount of sunshine than other biomes and when sunshine is greater the rate of water evaporation is also greater that results in more rainfall.
