Distribution of Living Things/Biomes

Question 1

It consists of broad regional groups of related manageable units called ecosystems.

Answer 1

Biomes

Question 2

The world is divided into manageable units

Answer 2

Ecosystems

Question 3

Different Types of Biomes

Answer 3

Dessert, Dessert soil, Grasslands, Forests, Tropical rain forest, Tropical seasonal forest, Temperate Deciduous forest, Temperate evergreen forest, Temperate rain forest, Temperate woodland, Coniferous forest, Savanna, Tundra, Taiga.

Question 4

It is a very dry, often barren biome characterized by temperature extremes and by widely spaced plants with thick waxy leaves and often protective spines.

Answer 4

Desert

Question 5

These are dominated by sage bush rabbit bush, and smaller perennial plants.

Answer 5

Cool deserts

Question 6

These are dominated by creosote, cactus, acacias, agave, and yuca.

Answer 6

Hot deserts

Question 7

It is largely unprotected by vegetation. It is subject to severe erosion from wind and occasional rain. It has a tin top layer of decaying plant materials called humus.

Answer 7

Desert soil

Question 8

It is dominated by grasses and a rich array of deep-rooted beautifully flowering non-grass species. They have a few trees because of inadequate and frequent grass fire that kills woody seedlings.

Answer 8

Grasslands

Question 9

This covers extensive areas in the interior of continents where there is enough moisture to support forest or woodland.

Answer 9

Temperate grasslands

Question 10

It is a region where trees grow as a result of adequate temperature and minimal precipitation of 75 centimeters or more.

Answer 10

Forest

Question 11

It is a forest with high, fairly constant rainfall and temperature that permits trees to grow throughout the year. Annual rainfall may exceed 400 centimeters. This is the biome with the highest species diversity. The number of species in a given area may have almost 100 different species per hectare.

Answer 11

Tropical rainforest

Question 12

It is also known as the monsoon forest. Seasonal rainfall is concentrated during a certain part of the year after which follows an increasingly pronounced dry season. The proportion of deciduous trees (trees that lose their leaves for a season) increases as the length of the dry season increases.

Answer 12

Tropical seasonal forest

Question 13

It is dominated by trees that lose their leaves each year

Answer 13

Temperate deciduous forest

Question 14

Occurs where the condition favors conifers or broad-leaved evergreen over deciduous trees. It has poor soil conditions, frequent droughts, and forest fires. Temperate evergreen plants include ponderosa and pine trees. These forests are found in Eastern Asia, Southern Chile, New Zealand, and Australia.

Answer 14

Temperate evergreen forest

Question 15

Occurs in cold climates near the sea with abundant winter rainfall and summer clouds or fogs. These include the forest of giant trees of the Pacific Coast of North America, and the mixed coniferous forests of Washington, Oregon, and California.

Answer 15

Temperate rainforest

Question 16

Occurs where the climate is too dry to support the forest yet provides sufficient moisture to support trees as well as grasses. Dominant trees are conifers, evergreens, flowering trees, and deciduous trees.

Answer 16

Temperate woodland

Question 17

A biome with a vast forest of coniferous trees growing at Latitudes cold snowy winters and short summers.

Answer 17

Coniferous forest

Question 18

Dry open grassland biome containing stunted widely spaced trees that is situated in tropical forest and desert.

Answer 18

Savanna

Question 19

Consists of grassland dotted with dotted with scattered small trees and shrubs such as acacia. Some savannas are entirely grassland; others contain many trees.

Answer 19

Tropical savanna

Question 20

It is a biome of low-growing plants where water reaches plant roots for only a few months of the year because the soil is frozen for the rest of the time.

Answer 20

Tundra

Question 21

It is dominated by conifers that can survive extreme cold in winter.

Answer 21

Taiga

Question 22

It has a tin top layer of decaying plant materials called

Answer 22

Humus

Question 23

The permanent frozen layer is

Answer 23

permafrost
