Questions and Answers
What are broadleaf trees?
Broadleaf trees have broad or wide leaves. They don't have needles or needle-like leaves like conifers and other evergreen trees.
What are trees in temperate deciduous forests like?
Trees in temperate deciduous forests have leaves that change colors and then lose their leaves when the seasons change.
What do temperate deciduous forests consist of?
A temperate deciduous forest may consist entirely of deciduous trees or it may also contain some conifers (a mixed forest).

Study Notes
Broadleaf Trees
- Broadleaf trees feature wide leaves, distinct from needle-like leaves of conifers and evergreens.
Temperate Deciduous Forest Characteristics
- Trees in these forests exhibit seasonal color changes, shedding leaves in autumn.
- Forests can be composed entirely of deciduous trees or mixed with conifers.
Geographic Distribution
- Commonly found in the eastern United States, stretching from Maine to Florida and reaching the Mississippi River.
- Also located in eastern Canada, western United States, western and central Europe, Russia, China, Japan, and both North and South Korea.
Climate and Ecosystem
- Characterized by four distinct seasons and consistent annual precipitation.
- Classified as a moist ecosystem or biome.
Ecological Definitions
- Each forest area is categorized by its dominant tree species.
- Key species in New England forests include sugar maple, beech, and yellow birch.
- Oak trees dominate southern forests, with oak and hickory in the far southern regions.
Factors Influencing Biodiversity
- Determining factors for species diversity include localized changes in temperature, precipitation, and soil conditions.
- Plants and animals adapt to seasonal changes in their environment.
Energy Flow in Ecosystems
- Energy flow begins with sunlight and photosynthesis, transferring through producers, consumers, and decomposers.
- The forest floor teems with life, marking a distinctive feature of broadleaf forests.
Ecosystem Structure
- Primary consumers are animals that feed directly on producers.
- Secondary consumers eat primary consumers, while tertiary consumers prey on secondary consumers.
Habitat Requirements
- The presence of broadleaf forests relies on specific precipitation levels and seasonal temperature variations.
- Notable producers include various tree types (maple, oak, beech), flowering plants, ferns, mosses, and shrubs.
Consumer Examples
- Consumers range from insects and small mammals to birds, deer, foxes, bobcats, wolves, bears, and sometimes even cougars and moose.
Cardinal Characteristics
- Cardinals are large, long-tailed songbirds with a thick bill and prominent crest.
- They are omnivorous, consuming seeds, berries, and insects.
- Unlike many birds, cardinals do not migrate and maintain bright plumage year-round.
