Concept explainers

Ecological adaptations

An ecological adaptation is any morphological, physiological, or behavioral trait of an organism that allows it to survive and reproduce in a habitat or ecosystem. Adaptation is a biological mechanism by which an organism gradually gets more acclimated to its surroundings.

The extremely low precipitation of subtropical desert biomes might lead one to expect fire to be a major disturbance factor; however, fire is more common in the temperate grassland biome than in the subtropical desert biome. Why is this?
Which of the following ground cover conditions contributes to the highest loss of topsoil and moisture? grasslands Otilled soil woodlands grain crops
Which of the following BIOTIC influence or potentially determine the vegetation biome of a terrestrial region? Grazing Amount of rainfall Mean temperature/length of growing season Mean temperature/length of growing season
General Patterns Found Across All Biomes Disturbance is important in determining the set of species found in an area. Naturally, broadleaf trees will replace longleaf pine trees, changing the forest from coniferous to deciduous. However, fire removes the broadleaf species, maintaining the coniferous forest. Before agriculture, the southeastern United States was dominated by longleaf pine, but now broadleaf trees are found where the great coniferous forests once grew. From this change in forest species, what do you know has happened to the frequency of fire in the southeastern United States? There are more forest fires in the southern United States now then there were in the past. There are fewer forest fires in the southern United States now then there were in the past.
What is an example of an area that is likely to undergo primary succession? O Land is bulldozed and soil remains Plants die from drought and decompose A forest fire occurs Glaciers melt and leave exposed rock
Identify the coldes, driest biome with relatively little or relatively small vegetation. The plants in this biome have characteristically short "growth habits," meaning that species like willows and other trees may be only a few inches tall.

Largest terrestrial biome on Earth chaparral Vertical layering is most 3. pronounced tropical rain forest Dominated by shrubs in midlatitude 4. coastal regions coniferous forest Seasonal and daily temperature 5. variability with very low tundra precipitation
Which of the following threats to terrestrial biomes is FALSE? O Exploration of oil and gas threaten both boreal forest and tundra ecosystems. O Climate change, farming practices, and overgrazing are leading to the desertification of tropical savannas. O Logging for timber poses a greater threat to tropical rain forests compared to effects of large-scale agriculture. O Human-mediated changes in the frequency and intensity of fire are threatening Mediterranean shrublands.
Which factor is least likely to contribute to distinct community boundaries? Strong climatic gradients Gradual changes in nutrient availability Sharp changes in soil type Human-made barriers
BIOMES OF THE WORLD Deciduous Forest Desert Tundra Taiga Grassland Mostly grasses, few trees seen Experiences all 4 seasons Plants and animals Coniferous tree conserve (store) water forest Extreme Only grasses are found here because of temperatures, very hot/very cold frozen ground High biodiversity Permanently frozen ground Leaves adapted into needles, Grazers are abundant here, zebra, giraffe, cow, deer evergreen trees
