9th Env Chapter 6.2 FOREST BIOMES OUTLINE
Question | Answer |
---|---|
FOREST | Of all biomes, ___________________biomes are the most widespread and the most diverse. |
RAINFALL | Yje large trees of forests need a lot of water, so forests can be found where |
TROPICAL TEMPERATURE CONIFEROUS | There are 3 main forests in the world______________________________ __________________ an ________________________(Taiga) |
TROPICAL RAIN FOREST | ________________________ _________________________are forests or jungles near the equator, They are characterized by large amounts of rain and little variation in temperature and contain the greatest known diversity or organism on Earth. |
REGULATE | They help_________________________ world climate an play vital roles in the nitrogen, oxygen, and carbon cycles. |
HUMID VARIETY | They are humid, warm, and get strong sulight which allows them to maintain a fairly constant temperature that is ideal for a wide variety of plants and animals. |
PLANTS | Most nutrients are within the_______, not the soil. |
DECOMPOSERS | ______________________- on the rain-forest floor break down dead organisms snd return the nutrients to the soil, but plants quickly absorb the nutrients. |
FUNGI TREE | vSome trees in the tropical rain forest support _______ that feed on dead organic matter on the rain-forest floor. In this relationship, the fungi transfer the nutrients form the dead matter directly to the ___________. |
WATER | Nutrients from dead organic matter are removed so efficiently that runoff from rain forests is often as pure as distilled_____________. |
LACK | Most tropical soils that are cleared of plants for agriculture___________ nutrients and cannot support crops for more than a few years. |
BUTTRESSES | Many of the trees form bove ground roots called__________or braces that grow sideways from the tree to provide it with extra support in the thin soil. |
LAYERS | In tropical rain forests, different types of plants grow in different _______________. |
four | There are _______ main layers of the rain forest: EMERGENT, UPPER, LOWER, UNDERSTORY |
EMERGENT LAYER | The __________________ ______________ is the top follge layer in a forest where the trees extend above surrounding trees. |
60-70m | Trees in this layer grow and emerge into direct sunlight reaching heights of _____ to __________m and can measure up to 5 m around. |
SNAKES | The animals such as eagles, bats, monkeys, and_______________ live in the emergent layer. |
CANOPY | The ______________ is the layers of treetops that shade the forest floor, amd is considered to be the primary layer of the rain forest. |
95 | The tall trees, more than 30 m tall, form a dense layer that absorbs up to _____________ percent of the sunlight. |
UPPER LOWEER | The canopy can be split into an _____________ and _____________ with the lower receiving less of the sunlight. |
EPIPHYTES | ___________________ are plants that use another plant for support but not for nourishment, and are located on high trees in the canooy. |
GROWING | ________________ on tall trees it allows them to reach the sunlight needed for photosynthesis, and to absorg the water and nutrients that run down the tree after it rains. |
CANOPY | Most animals that live in the rain forest live in the ___________ because they depend on the abundant flowers and fruits that grow there |
UNDERSTORY | The ____________ understory is the foliage layer that is beneath and shaded by the main canopy of a forest. |
LITTLE | ____________ light reaches this layer allowing only trees and shrubs adapted to shade to grow them. |
3.5m | Most plants in the understory do not grow more than_______m tall. |
FLAT | Herbs with large _______ leaves that grow on the forest floor capture the small amount of light that penetrates the understory. |
DIVERSITY | The _________ of rain forest vegetation has led to the evolution of a diverse community of animals. |
SPECIALISTS | Most rainforest animals are ________________ that use specific resources in particular ways to avoid competition and have adapted amazing ways prey and avoid predators. |
INSECTS | __________________- use camouflage to avoid predators and may b shaped like leaves or twigs. |
MINUTE OIL | Every____________ of every day, 150 acres of tropical rainforest are cleared for logging operations, agriculture, and oil exploration, |
HABITAT DESTRUCTION | ________________________ _________________________- occurs when land inhabited by an organism is destroyed or altered. |
RISKS | If the habitat that an organism depends on is destroyed, the organism is at ____________________ of disappearing. |
50 MILLION | An estimated __________ ______________ native peoples live in tropical rain forest and are also threatened by habitat destruction. |
LEAVE | Because they obtain nearly everything they need from the foret, the loss of their habitat could them to ___________ their homes and moveinto cities. |
CULTURE | This drastic change of lifestyle may then cause the native peoples to lose their ______________________ and traditions, |
