Which of the following factors would have the least impact on a deep sea hydrothermal vent community quizlet?

Which of the following factors would have the LEAST impact on a deep-sea hydrothermal vent community? Reason: Solar energy, or sunlight, would not be significant in deep seas. Unlike most ecosystems, deep-sea vent communities are not directly supported by energy from the sun. You just studied 18 terms!

What is the basis for the recognition of the intertidal zone?

What is the basis for the recognition of the Intertidal zone? The intertidal zone is flooded at high tide and dry during low tide. After an increase in nutrients due to sewage contamination, a lake often becomes inhospitable to fish.

What is the primary source of energy for nearly all of Earth’s ecosystems quizlet?

What is the primary source of energy for nearly all of the earths ecosystems? Solar energy from sunlight captured by chlorophyll.

What is a unique feature of many plants that inhabit tropical forest such as orchids?

` What is a unique feature of many plants that inhabit tropical forests, such as orchids? They are epiphytes. “Mediterranean” is another name for this type of biome.

What helps produce the patchiness found in most biomes?

What natural phenomenon maintains the presence of grasslands?

What natural phenomenon maintains the presence of grasslands? periodic drought and fires.

What are the main features of tropical rainforest?

The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness). Rainfall: The word “rainforest” implies that these are the some of the world’s wettest ecosystems.

Why do tropical forests have a great variety of plants and animals?

Climate: because rainforests are located in tropical regions, they receive a lot of sunlight. … Since there is a lot of sunlight, there is a lot of energy in the rainforest. This energy is stored in plant vegetation, which is eaten by animals. The abundance of energy supports an abundance of plant and animal species.

What are the main characteristics of tropical rainforest?

Characteristics of tropical rainforests
  • Very wet with over 2,000 mm of rainfall per year.
  • Very warm with an average daily temperature of 28°C. The temperature never drops below 20°C and rarely exceeds 35°C.
  • The atmosphere is hot and humid .
  • The climate is consistent all year round. There are no seasons.

What are the main layers of a tropical rainforest?

Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor. Each layer has unique characteristics based on differing levels of water, sunlight, and air circulation.

How do tropical rainforests contribute to the overall health of the biosphere?

As well as the vivid beauty that comes with great diversity in plants and animals, rainforests also play a practical role in keeping our planet healthy. By absorbing carbon dioxide and releasing the oxygen that we depend on for our survival. The absorption of this CO2 also helps to stabilize the Earth’s climate.

What is in a tropical rainforest?

The tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation that form three different layers. … They climb trees in the canopy to reach for sunlight. The middle layer, or understory, is made up of vines, smaller trees, ferns, and palms.

What are the three layers of a tropical rainforest?

Structure – The tropical rainforest is composed of three layers: the canopy, the understory, and the forest floor. The canopy is formed from the large trees whose crowns form a tight, continuous layer above the ground. The canopy is home to 90% of organisms found in the rainforest!

Which adaptation would be most helpful in a tropical rainforest?

The first and most common animal adaptation in a tropical rainforest is camouflage. For an animal to successfully exhibit this adaptation, it needs not only to have a color that will help it blend into the environment but also a shape that is unrecognizable by its predator.

What is the emergent layer of the rainforest?

EMERGENT LAYER

The tallest trees are the emergents, towering as much as 200 feet above the forest floor with trunks that measure up to 16 feet around. Most of these trees are broad-leaved, hardwood evergreens. Sunlight is plentiful up here. Animals found are eagles, monkeys, bats and butterflies.

What are two layers of a tropical rainforest?

  • Tropical rainforests have four layers:
  • Emergent Layer. These giant trees thrust above the dense canopy layer and have huge mushroom-shaped crowns. …
  • Canopy Layer. The broad, irregular crowns of these trees form a tight, continuous canopy 60 to 90 feet above the ground. …
  • Understory. …
  • Forest Floor. …
  • Soil and Nutrient Recycling.

Why does the rainforest have 4 layers?

Rain forests are divided into four layers, or stories: emergent layer, canopy, understory, and forest floor. Each layer receives a different amount of sunlight and rainfall, so different types of animals and plants are found in each layer.

What are the 5 layers of the rainforest?

Primary tropical rainforest is vertically divided into at least five layers: the overstory, the canopy, the understory, the shrub layer, and the forest floor. Each layer has its own unique plant and animal species interacting with the ecosystem around them.

Why is it called the emergent layer?

The top layer of a rain forest is called the emergent layer. This layer receives bright sunlight and plenty of rain, and is also very windy. The tallest trees rise above every other plant to a height of 230ft (70m). Animals in this layer, such as monkeys, are agile, with a good sense of balance.

What is the ground layer of a rainforest like?

Ground level – contains less vegetation due to the dark, damp conditions, a thick layer of decomposing leavesand the buttress root of trees. … Contains tall trees, climbing plants like vines and lianas . 50% of rainforest life is found here. Emergent – contains the tallest trees emerging out of canopy.
