Animals

Is It an animal? Animals are many celled. The different cell carry out different functions: sensing the environment, excreting wastes, and reproducing. Animal cells are Eukaryotic: What does Eukaryotic mean? Animals are Heterotrophs: What does this mean? Animals digest their food. They break the food down into simple molecules that can move into the cells. What do we call the breaking down of food make energy? Animals move from place to place Animals are capable reproducing sexually, and some reproduce asexually.

How animals meet their needs Animals have adaptations they inherited from previous generations. What are some of the adaptations we learned that plants adapted for survival? Why do organisms adapt overtime? Animals all have a basic need for food. Herbivores: eat only plants or parts of plants. They eat in great abundance because plants don’t supply as much energy as the flesh of other animals. Turn to your partner and share an animal you know that is an herbivore. Carnivores: These animals capture and kill their prey for food. Omnivore: These animals eat both plants and animals Detritivores: Are animals that feed off of tiny bits of decaying matter

Physical Adaptations Some prey have physical features that enable them to avoid predators. Hissers have protective plates. Some have quills, shells, size, blend into their surroundings (Pepper moths, are brown and look like lichen on trees) Camouflage: are any markings that help the animal blend, some can actually change color depending on their surroundings.(chameleon)

Predator Adaptations Camouflage: his enables predators to sneak up on their prey. (Think about the preying mantis) Behavior adaptations: Animals also can use chemicals produced internally to escape predators. Skunks spray Ants and beetles can also spray a stinky chemical Octopus, when they feel threatened, release a cloud of ink. Some can move fast and other move together in herds to resemble a large animal.

Animal Classification

Animal classification All animal in the animal kingdom have similarities, but animals are broken down into two major groups: Vertebrates: Animals with backbones. Their backbones are made up of structures called vertebrae, which support the animal. The vertebrae also protect the spinal cord. Invertebrates: Animals without a backbone. 97% of all animals are invertebrates

Symmetry After determining if the animal has a backbone or not, scientists check for the animal’s symmetry. Symmetry: is how the body parts of an animal are arranged Asymmetrical: animals with no definite shape.( Sponge) Radial Symmetry: animals with body parts arranged in a circle around a center point.( jelly fish, sea urchins, star fish) Bilateral Symmetry: animals whose body can be divided into left and right halves, that are near mirror images of each other.
