Food chain - linked in order they eat

Food web - shows how energy moves

Finding amount of kcal needed to maintain body weight - amt of kcal needed to maintain weight per day/how much it weighs

Energy pyramid

Tertiary - 750kcal

Secondary - 7,500kcal

Primary - 75,000kcal

Producers - 750,000kcal

If only 10% of energy moving to the next tropic level, the rest of the energy is used in heat loss, growth, egressed waste, and respiration

Differences in digestion between herbivores, omnivores, and carnivores

Herbivores - long digestive system length, big cecum

Omnivore - medium digestive system length, small cecum

Carnivore - short digestive system length, small or no cecum

Differences in teeth between herbivores, carnivores, ad omnivores

Herbivores - flat teeth, big incisors, small canines

Omnivores - pointed and flat teeth, medium canines and incisors

Carnivores - sharp teeth, big canines, small incisors

Characteristics of life

Organization - structure of living things, parts arranged and coordinated to keep living.

Homeostasis - regulate internal environment. Ex - sweating in heat

Metabolism - body continues process of converting food. Ex photosynthesis in plants

Reproduction - create offspring and reproduce. Ex - 2 cats mating and having kittens

Growth and development - grow based on instructions coded for by genes. Ex - tadpole to frog

Response to stimuli - reaction to what causes change in state. Ex - seeking shade when hot

Evolution - change in heritable traits of population over successive generations. Ex butterfly evolving eyespots on wings over time.
