Large, active reptiles, such as non-avian dinosaurs, went extinct before the start of the Cenozoic. Hence, dinosaurs, pterosaurs, and other such reptiles are not characteristic of the Cenozoic.
In nearly all biomes, the dominant (must numerous) form of wildlife are insects. The weight of all insects found in a region is far greater than all other animals combined. Ants and termites make up the greater number of insects in the desert.
Most reptiles and insects eat far less compared to mammals and birds as they are much less active and use less energy to generate body heat.
Reptiles are vertebrates with bodies covered with scales..They Absorb heat from the environment,but they avoid very high and very low temperatures.During winter some Reptiles hibernate.Reptiles that live in dessert share active at night when the temperature is lower.
Meerkats are day-active, and will spend most of the day(when it isn't too hot) searching for food and eating it as they find it. primarily insects, but also small reptiles, lizards, and vegetation
Centipedes are active hunters, and they look around for smaller insects or spiders to eat. Rarely, a centipede will attack a larger prey. Where there is no prey, they will consume certain types of plants that have some of their necessary proteins. They eat insects, spiders, and other small invertebrates. If the centipede is large enough it will even attack small vertebrates like lizards.
There are hundreds of species of nocturnal animals. These includes birds (owls), mammals (bats, mice, etc.), some reptiles, and many kinds of fish).
Crepuscular animals and rays are mosquitoes, dogs, cats, nighthawks, moose, rabbits, ferrets, mice, rats, and squirrels.
Reptiles or animals that are ectotherms such as lizards,snakes & crocodiles gain their warmth from sunlight. That is why they are very energetic after lazing around in the sun.
Well not all animals are always active. Some animals are active in the day and some are active at night. Why do you ask this?
because spiders are very active then
yes they are!Answer:Plants, insects and animals are only "pests" when they are where people find them inconvenient. Ants at picnic or in your larder are pests. Ants removing dead animals in the forest are parts of an active and healthy ecosystem.
