Leaves get their colors through pigments. Leaves turn green because of chlorophyll but when they turn orange red and yellow it’s the chlorophyll breaking down and mixing with pigments (like carotenoids)
It is A both chemical changes and flow of energy
Answer:
Fluid lava (which is less viscous because it has less silica content) flows much further than viscous lava (that is high in silica content). Therefore, this types of lava forms shield volcanoes – low slopes and low height- because they flow over longer distances before they cool. Viscous lava from composite volcanoes that are high in height and have steep slopes.Explanation:
<u>Temperature, humidity and elevation </u>are the two major factors determining the distribution of terrestrial biomes.
- A region of land with a similar climate and comparable plant and animal communities is referred to as a terrestrial biome. Different terrestrial biomes are typically described in terms of the trees, shrubs, and grasses that inhabit them.
- The Terrestrial biome type is influenced by variables including latitude, humidity, and elevation:
- A Terrestrial biome's latitude indicates how far it is from the equator. You will find the Arctic, boreal, temperate, subtropical, and tropical biomes as you move from the poles to the equator
- The amount of water in the air is known as humidity. Humid air is defined as having a high concentration of water vapor.
- The biomes will be referred to as semi-humid, semi-arid, or arid as we move away from the most humid environment (the driest).
- Elevation refers to the elevation of land above sea level. It becomes chilly.

Answer:
Many plant crops need more phosphorus than is dissolved in the soil to grow optimally. In addition, crops are usually harvested and removed – leaving no decaying vegetation to replace phosphorus. Therefore, farmers replenish the phosphorus ‘pool’ by adding fertilisers or effluent to replace the phosphorus taken up by plants.
