A component found in plants that allowed land plants to grow tall and outcompete simpler plants.
Vascular tissue (xylem and phloem)
The structure found in gymnosperms and angiosperms which allowed them to be the dominant plant forms on the planet.
Seeds
The branch of ecology that would take into account interactions between colonies of chimpanzees.
Population Ecology
The type of interaction seen through the interaction of a honey bee and sunflower in which the bee gains nectar and the sunflowers are pollinated.
Mutualism
The means by which energy enters ecosystems.
Solar Radiation
A derived characteristic for all land plants
Alternation of generations, walled spores, multicellular gametangia, apical meristems
The phylum for the Virginia state flower: Flowering Dogwood.
Anthophyta
The biome characterized by a breeding ground for many oceanic fish as they swim up to covered areas which involve a transition area between sea and river.
Estuary
The type of climate studied by looking at the community within the inside of a hollow log.
Microclimate
A human action that can lead to a species' extinction vortex
Overharvesting, Introduced Species, Habitat Destruction, Global Changes
The dominant generation of ferns and their chromosome category.
Sporophyte; Diploid
The structure within flowers that is the stalk of the stamen.
Filament
A limiting factor for the sardine population as density rises.
Predation, Competition, Disease
The trophic level assigned to an coyote in the following food chain:

Tertiary Consumer
The population with the most biomass in the following food chain:
Grasshopper --> Squirrel --> Owl
Grasshopper
A phylum of plants without vascular tissues
Bryophyta, Anthocerophyta, Hepatophyta
Angiosperms with parallel leaf veins and one cotyledon.
Monocot
The population selection done by manatees where gestation lasts 13 months and cows often only have one calf.
K-selection
An example of a keystone species of our temperate broadleaf forest.
Oak tree, hickory tree, coyote, owl, etc.
The location at which nature reserves are ideally established
Biodiversity Hotspot
