Describe how the available energy in the marine ecosystem of the Pacific Northwest could be different than that of African savanna.
Answer:
Savannah is located near the equator has more energy availability.
Explanation:
Maine ecosystem of the pacific northwest consists of open ocean and is influenced by the seasonal upwelling events and has freshwater and saline water bodies. It has an average temperature of 39 °F but is warmer near the equator. While the African savanna is a tropical grassland ecosystem and has warm temperature year-round is characterized by grasses and dispersed trees. The sunlight easily reaches the ground and the vegetation is dense and the climate usually warm with 20 to 30° C with an annual rainfall of 30 inches per year.The African savanna has more available energy than the marine ecosystem of the Pacific Northwest.
The African Savannah is an ecosystem that is characterized by:
warm temperatures throughout the year,grasses and small or dispersed trees that do not form a closed canopy, andhighest seasonal rainfall in the summer.The Pacific Northwest is a marine ecosystem that is characterized by:
mixture of climates andabundance of mountain ranges.The African Savannah has more available energy than the marine ecosystem of the Pacific Northwest because it is closer to the equator than the marine ecosystem of the Pacific Northwest.
Therefore, the African savanna has more available energy than the marine ecosystem of the Pacific Northwest.

What is the speed of a wave with a frequency of 2 Hz and a wavelength of 87 m?
Group of answer choices
0.023 m/s
43.5 m/s
89 m/s
174 m/s
The speed of a wave with a frequency of 2 Hz and a wavelength of 87 m will be 174 m/s. Thus, the correct option will be D.
What is Wave speed?Wave speed can be defined as the magnitude of distance which the wave travels in a given amount of time, such as the number of meters which it travels per second of time.
Wave speed is a scalar quantity as it has only magnitude and no direction. Speed of a wave depends upon the medium in which the wave travels.
The wave speed is directly proportional to the wavelength of the wave and the frequency of the wave. Speed of a wave is the product of its wavelength and frequency. The expression for wave speed is as follows:
Speed of wave = Wavelength × Frequency
Speed of wave = 87 × 2
Speed of a wave = 174 m/s.
Therefore, the correct option will be D.

disrupt ecosystems?
A. They can outcompete native species.
B. They cannot be killed by any of the
organisms in the environment.
C. They enhance the environment they
оссиру.
Answer:
A. They can outcompete native species.
Explanation:
Remember that ALL species need an ecosystem they can easily adapt in to survive, especially invasive ones. Adaptation is a heritable trait that helps organisms adjust to new changes in their environment.
Invasive species can compete with native organisms for resources, cause extinctions, reduce biodiversity, and disrupt ecosystem processes. They can also threaten, or even prevent human use of the resources in the ecosystem.
In order for an invasive species to be successful in their new environment, they need to be able to reproduce and grow rapidly to take over quickly.

Nutrients move through an ecosystem as nutrients are recycled through closed loops called biogeochemical cycles and are used over and over. The correct option is C.
What are nutrients?Nutrients are the substance that is needed by the body for energy and growth. These nutrients are present in food materials. These food materials are fruits, vegetables, etc.
An ecosystem is a place where all living organisms are lives and interact with each other. The ecosystem contains all resources that are needed by the organism.
As heterotrophic organisms, eat other animals and plants. The nutrients move from one organism to another organism.
Thus, the correct option is C. Nutrients are recycled through closed loops called biogeochemical cycles and are used over and over.

Why are carbon reservoirs important in the carbon cycle?
Answer: Carbon compounds regulate the Earth's temperature, make up the food that sustains us, and provide energy that fuels our global economy. Most of Earth's carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.
Carbon compounds govern the Earth's temperature, provide food for us to eat, and provide energy to power our global economy.
What is carbon cycle?The carbon cycle is nature's method of recycling carbon atoms, which travel from the atmosphere into organisms on Earth and then back into the atmosphere.
Carbon is found in carbon dioxide, a greenhouse gas that works to trap heat near the Earth.
It assists Earth in retaining the energy it receives from the Sun, preventing it from escaping back into space. The Earth's ocean would be frozen solid if it weren't for carbon dioxide.
The ocean, geologic reserves of fossil fuels, the terrestrial surface, and the atmosphere are the primary carbon reservoirs. Reservoir sizes are estimated in trillions of kilograms of carbon.
Thus, the carbon reservoirs are important in the carbon cycle.

Answer:
Hope it helps!~ (Sorry I you get it wrong or I got It wrong-)
Explanation:
Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. ... Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants.

What factor causes a mudslide?
Disturbances in the inherent stability of a slope generate landslides. They may occur in conjunction with severe rainfall or as a result of droughts, earthquakes, or volcanic eruptions. Mudslides occur when water accumulates quickly in the ground, causing a rush of water-soaked rock, soil, and debris.
Answer:
Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.
