How are mountain ecosystems like islands of biodiversity?
How are mountain ecosystems like “islands of biodiversity”? What other island-like habitats are there? They are full of endemic species. Tropical rainforests are another island-like habitat.
How human activities have affected the world’s deserts grasslands forests and mountains?
Describe how human activities have affected the world’s deserts, grasslands, forests, and mountains. … Ways that we have affected grasslands include: conversion to cropland, release of CO2 to atmosphere from burning grassland, overgrazing by livestock, and oil production and off-road vehicles in arctic tundra.
Which ecosystem is likely to provide fertile soils and good climate for growth of temperate summer crops?
The biome best suited for both raising crops and grazing livestock would be temperate grasslands. The temperature in the winters may be cold but during summers it is hot had dry and as deep and fertile soils that make them wildly used for growing crops and grazing cattle.
Why does a thick layer of decaying litter typically cover the floors of temperate deciduous forests?
Why do temperate deciduous forests typically have a thick layer of decaying litter? Because they have cooler temperatures and fewer decomposers than tropical forests have, these forests also have a slower rate of decomposition. As a result, they accumulate a thick layer of slowly decaying leaf litter.
Why mountain region is rich in biodiversity?
Biodiversity is high in mountain regions because of their wide range of habitats, varied micro-climates, and ecological conditions. These factors have resulted in a high degree of genetic diversity in terms of crop and livestock species and their wild relatives.
How does climate affect the nature and locations of biomes?
Because climate determines plant growth, it also influences the number and variety of other organisms in a terrestrial biome. Biodiversity generally increases from the poles to the equator. It is also usually greater in more humid climates.
Which ecosystem makes up approximately 70% of the earth’s surface?
The ocean is a continuous body of salt water that covers more than 70 percent of the Earth’s surface. Ocean currents govern the world’s weather and churn a kaleidoscope of life. Humans depend on these teeming waters for comfort and survival, but global warming and overfishing threaten Earth’s largest habitat.
How does climate and vegetation vary with latitude and elevation?
Climate varies with latitude and altitude. For example, climate gets colder as latitude and altitude increase. So, climate also gets colder as you move farther up a mountain. As latitude and altitude increase, biomes and vegetation change.
Why do those regions whether tropical desert or temperate which include high mountains tend to be the most biologically diverse?
2.3-1. Why do those regions, whether tropical, desert, or temperate, that include high mountains tend to be the most biologically diverse? … Greater rainfall, higher average temperatures, and higher levels of biological activity all contribute to higher rates of nutrient depletion in tropical rain forest soils.
What biome has most fertile soil?
The biome that has the richest soil is a) temperate grasslands. Temperate grasslands are characterized by the grasses that dominate the landscape,…
