I'm thinking it might be fossil evidence. Hope it helps!

Mouth
Teeth chop food & saliva breaks down food
Esophagus
Tube that connects mouth to the stomach (peristalsis)
Stomach
Organ that releases acid and juices & mixes with food to create chymes
Small Intestine
Greatest amount of digestion takes place (if taken out, it would be 21ft long) (takes 4hrs to get to the small intestine)
Liver
Gland that releases bile and filters poisonous waste
Gall Bladder
Small organ that stores bile (you can live without it)
Pancreas
Gland that produces digestive enzymes and insulin
Large Intestine
(colon) Tube extending the small intestine where your indigestive food is ready for elimination
Rectum

Explanation:
The organs of the digestive system are the mouth, esophagus, stomach, pancreas, liver, gallbladder, small intestine, large intestine and anus. Recognizing how these organs work together to digest food is key to understanding how digestion works.
Organisms are made up of a bunch of cells. Billions of cells coming together make up an organism.
1.each of several hierarchical levels in an ecosystem, comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.
A scavenger is an organism that mostly consumes decaying biomass, such as meat or rotting plant material. Many scavengers are a type of carnivore, which is an organism that eats meat. While most carnivores hunt and kill their prey, scavengers usually consume animals that have either died of natural causes or been killed by another carnivore.
Scavengers are a part of the food web, a description of which organisms eat which other organisms in the wild. Organisms in the food web are grouped into trophic, or nutritional, levels. There are three trophic levels. Autotrophs, organisms that produce their own food, are the first trophic level. These include plants and algae. Herbivores, or organisms that consume plants and other autotrophs, are the second trophic level. Scavengers, other carnivores, and omnivores, organisms that consume both plants and animals, are the third trophic level.
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.
Answer:
gymnosperms produce male cones and female cones, and the pollen from a male cone fertilize the egg inside a female cone
