Energy in Food
the main source of energy for all living things
what is the sun?
plant structure that helps bring materials in the air to the plant
what are leaves/stomata
an animal that uses stored energy in its body to keep its body temperature within a normal range
what is an endotherm?
new plants are made mostly of these three elements
what are carbon, oxygen, and hydrogen
an animal that eats only plants
What is an herbivore?
herbivores obtain energy by
what is eating producers
materials brought into the plant during photosynthesis
what are carbon dioxide and water
this type of animal gets energy to warm its body from the sun
what are ectotherms?
plants use these three nutrients in the soil for growth
what are nitrogen, potassium, and phosphorous
an animal that eats both plants and animals
what is an omnivore?
name the trophic levels in an ecosystem, from bottom to top
what are (4) producers (3) primary consumers (2) secondary consumers (1) tertiary consumers
materials produced by the plant during photosynthesis
what are oxygen and glucose
smaller, more active endotherms break down energy faster, and therefore have a faster one of these
what is metabolism?
reptiles, insects and most fish are considered what?
what are ectotherms
the chemical processes animals use to break down or build molecules
what is metabolism?
answers will vary... students must name an animal that eats only plants
matter that plants use for photosynthesis comes from
what are the air and water?
two ways an animal uses energy that cannot be seen
what are:
- grow
- heal
- lungs, heart, kidneys, other organ functions
this group of animals is at the top of the pyramid in a trophic level
what are tertiary consumers
define photosynthesis
what is the process that plants use to make glucose using carbon dioxide, light, water, and producing oxygen
seedlings are able to sprout when there is little sunlight available underground due to this
what is stored sugar and starches (food)
plants make glucose by doing this
there are two types of body movements called...
what are locomotor and nonlocomotor movements
define cellular respiration
what is the process that stored energy in food is converted to chemical energy in an animal's body, that chemical energy is then transferred to the animal's cells
define chlorophyll
a substance that absorbs sunlight energy and makes plants green
