Energy in this ecosystem passes directly from the sun to.
Answers
Answer:
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement.

How does sea level change when Earth's global temperature is lower?
A. Glaciers grow bigger, causing sea level to fall.
B. Glaciers grow smaller, causing sea level to fall.
C. Glaciers grow smaller, causing sea level to rise.
D. Glaciers grow bigger, causing sea level to rise.
Answers
Glaciers grow smaller, causing sea level to rise when Earth's global temperature is lower. Thus, the correct option is C.
Sea level lowers during cold climate periods, known as glacial epochs or ice ages, due to a shift in the global hydrologic cycle, in which water evaporates from the oceans and is stored on the continents as massive ice sheets, extended ice caps, ice fields, and mountain glaciers. At the last glacial maximum, some 20,000 years ago, global sea level was about 125 meters lower than it is today.
What is interglacial epochs?Because the melting North American, Eurasian, South American, Greenland, and Antarctic ice sheets returned their stored water to the world's oceans as the climate warmed, sea level rose. Sea level is at its highest during the warmest eras, known as interglacial epochs.
We are currently living in the most recent interglacial, which began around 10,000 years ago and is referred to by geologists as the Holocene Epoch. Sea levels were about 3 to 20 meters higher than they are now during several previous interglacials.

Jayden is researching the Earth's
plates. How would he describe the
relationship between the Earth's plates
and soil and rocks?
Answers
Answer:
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
The Earth's plates have a crucial relationship with soil and rocks. This connection is characterized by the plates' movement influencing the formation, distribution, and composition of soil and rocks across the planet.
The asthenosphere, which is semi-fluid beneath them, is separated into many tectonic plates that make up the Earth's lithosphere. Convective currents in the mantle cause these plates to move constantly. Processes like subduction, in which one plate falls beneath another, and rifting, in which plates move apart, are fueled by this movement. Mountains, valleys, and oceanic basins are all the result of these dynamic processes, which have a significant impact on the surface of the Earth.
Through volcanic activity and metamorphism, interactions between the plates also aid in the production of different types of rocks. Therefore, the distribution and makeup of soils and rocks on our globe are significantly shaped by plate movement, which also has an impact on landscapes, ecosystems, and geological characteristics.

B. Consumers pass on 20% of the energy they get from a lower trophic level.
C. Primary consumers lose 60% of the energy they absorb from producers as urine and feces.
D. 10% of the energy Primary consumers absorb is lost as heat.
Answers
The community along with the biotic and abiotic factors makes the ecosystem. In the ecosystem, 10% of the energy primary consumers absorb is lost as heat. Thus, option D is correct.
What is an ecological pyramid?An ecological pyramid is the graphical presentation of the organism and the flow of energy at each trophic level. The trophic level constitutes the producers and the consumer.
The flow of energy follows the 10% energy rule where each trophic level loses and gains only a certain amount of heat. The heat is lost as excretory products in the environment.
The maximum amount of energy is gained by producers which passes to the primary consumers (10%), secondary consumers (1%), and the upper trophic level.
Therefore, option D. primary consumers absorb only 10% of energy.
