all organisms can be divided into these two major groups
flowering & nonflowering
two major divisions of plants
vertebrates can be divided into these groups based on physical characteristics
Fish, amphibians, reptiles, birds, and mammals (FAR Big Mama!)
breathe through gills, most have scales & fins, lay eggs, and have body temperature that changes w/ the environment
1st part of life - breathe through gills & spend in water, adults breathe with lungs on land. Smooth moist skin, most lay eggs, have body temp that changes w/ environment
breathe with lungs, have scales or plates, most lay eggs, have body temp that changes with the environment
have feathers, beak, wings, feet, lay eggs, constant body temperature
breathe with lungs, fur or hair, nurse young with milk, birth to live offspring (usually), constant body temp
animals without backbones
invertebrates with hard outer shell (exoskeleton)
insect, crabs, clams
invertebrates without hard outer shell
spiders, shrimp, crayfish, sponges, sea stars, snails
surroundings where an organism lives
characteristics in a distinct environment
influences what organisms can be found there

what do senses help animals do?
keep out of danger, find food & shelter
sense in bats using sound to figure out location in the dark
characteristics that come from the parents - typically physical
characteristics that animals get during their lifetime - mainly behavioral
mainly inherited (passed from parents to offspring). Examples would be type & shape of body coloring, type & shape of body structure, sensory organs, etc.
a response to a change in the environment. Seen in both plants & animals.
Plant responses to light, water, gravity, and touch. Examples; roots growing down & stems growing up, vines growing up a support, leaves growing towards light
These are animal behaviors that allow them to survive. Examples are ducks knowing how to swim without being taught, birds building nests without being taught, and animals hibernating or migrating without being taught
change in behavior resulting from and shaped by specific experiences. Examples are; dogs learning to roll over on command, bears learning to fish for food, etc.
specific and distinctive ways that plants and animals act in order to survive within a specific ecosystem
Examples of behaviors
how animals eat, sleep, and communicate. How plants reproduce or get what they need to make food
Patterns of behaviors
specific sets of behaviors related to the environment the animal lives in. CHANGES in the environment can cause changes in the behaviors.
These are related to other organisms present, the availability of food & other resources, and the physical characteristics of the environment
Changes, which can be beneficial or harmful
caused in the environment by organisms living there
