Human impact on the environment or anthropogenic impact on the environment includes impacts on biophysical environments, biodiversity, and other resources. The term anthropogenic designates an effect or object resulting from human activity.
Animals can be divided broadly into vertebrates and invertebrates. Vertebrates have a backbone or spine (vertebral column), and amount to less than five percent of all described animal species. They include fish, amphibians, reptiles, birds and mammals. The remaining animals are the invertebrates, which lack a backbone. These include molluscs (clams, oysters, octopuses, squid, snails); arthropods (millipedes, centipedes, insects, spiders, scorpions, crabs, lobsters, shrimp); annelids (earthworms, leeches), cnidarians (jellyfish, sea anemones, corals), and sponges.
(Answer #1). One of the most basic ways of categorizing animals is to break them down into animals with backbones and animals that do not have backbones. The animals that have backbones are called vertebrates. This word comes from the word that we use for the bones that make up the backbone.Those bones are called vertebrae so the animals are vertebrates. The animals that do not have backbones are called invertebrates.Some examples of vertebrates include human beings, cats, dogs, fish, elephants, and chickens. Some examples of invertebrates include spiders, worms, and flies. krishna-agrawala | College Teacher | (Level 3) Valedictorian.
