What environmental reason is responsible for an observed decrease of maple syrup in the Northeast United States? Temperature increase.

What would be evidence for lower or decreased temperature affecting plant species in a mountainous region?

What would be evidence for lower or decrease in temperature effecting plant species in a mountainous region? Migration of plant species to a higher elevation.

what would be evidence for increased temperature affecting plant species in a mountainous region? migration of plant spices to a higher elevation.

Why would a plant species go extinct but an animal survive when temperature change alters a habitat?

Why would a plant species go extinct but an animal survive when temperature change alters a habitat? … Plants are less tolerant of rapid temperature change.

Why are increasing temperatures in the Arctic a threat to polar bears quizlet?

Why are increasing temperatures in the Arctic a threat to polar bears? Polar bears may drown looking for sea ice.

What is the greenhouse effect?

Greenhouse gases

The greenhouse effect: some of the infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds. The effect of this is to warm the Earth’s surface and the lower atmosphere.

What evidence supports an increase in Earth’s surface temperature quizlet?

What evidence supports an increase in the Earth’s surface temperature? Migration of plant species to a higher elevation.

How does climate change affect where plants are distributed?

Increases in atmospheric CO2 concentration affect how plants photosynthesise, resulting in increases in plant water use efficiency, enhanced photosynthetic capacity and increased growth. Increased CO2 has been implicated in ‘vegetation thickening’ which affects plant community structure and function.

How does climate affect the distribution of plants?

Climate controls the distribution of many plants (1, 2). Future changes in climate are projected to cause changes in vegetation distribution (3). … Studies of plant phenology have attributed longer growing seasons, earlier onset of flowering, and earlier harvest to climate warming (5, 6).

How does climate influence the distribution of plants?

The plant community in an area is the most sensitive indicator of climate. Regions with not much rainfall and scarce vegetation are called deserts, or arid regions. … Areas with somewhat greater rainfall are called semiarid regions.

How does environmental change affect the survival of a species?

Species are already being impacted by anthropogenic climate change, and its rapid onset is limiting the ability of many species to adapt to their environments. … In addition to increased rates of disease and degraded habitats, climate change is also causing changes in species themselves, which threaten their survival.

How the environment affects the extinction and evolution of species?

Extinction is often caused by a change in environmental conditions. When conditions change, some species possess adaptations that allow them to survive and reproduce, while others do not. If the environment changes slowly enough, species will sometimes evolve the necessary adaptations, over many generations.

How do changes in the environment affect species extinction?

Instead, climate change was found to typically lead to local extinctions and declines by influencing interactions between species, such as reducing prey populations for predators. … However, where causes have been identified, changing species interactions have been found to be key in the majority of cases.

Why are freshwater ecosystems biologically important quizlet?

An important characteristic of each biome is its (blank), or the number and variety of different biological species that live there. … Why are freshwater ecosystems biologically important? A. They support high levels of biodiversity.

How do greenhouse gases get into our atmosphere?

The quantity of greenhouse gases is increasing as fossil fuels are burned, releasing the gases and other air pollutants into the atmosphere. Greenhouse gases also make their way to the atmosphere from other sources. Farm animals, for example, release methane gas as they digest food.

What evidence supports an increase in Earth’s surface temperature?

Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks.
