Answer and Explanation:
During the whole biota history, there occurred extinctions due to different reasons.
During the Cretaceous, which took place between 145-65 million years ago, there occurred a massive extinction that eliminated most of the species on the Earth. Many of the characteristic groups of this period were affected. Dinosaurs, Plesiosaurs, Ammonites, Tricodonts, Cycas, Gynkgos, Conifers, the recent angiosperms, birds, and mammals.
The extinction was caused by the volcanic eruptions, and the unusual fall of many different asteroids, which caused important changes on the Earth´s surface. The consequent climatic change was what ended affecting all the species directly. The extinction was gradual, although it occurred in a short geological lapse of time.
1. Describe the main pathways of the water cycle, including
how water enters and leaves the atmosphere.
Answer:
Enjoy your free answer
Explanation:
Liquid water evaporates or the process of transpiration, forming water vapour that moves through the atmosphere, then comes down as precipitation, either enters the soil or transfers onto the lakes, rivers, oceans, etc.

What is water cycle?The water cycle, also known as the hydrologic cycle or the hydrological cycle, is a biogeochemical cycle that describes the continuous movement of water on, above and below the surface of the Earth.
Moreover, the water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
Therefore, the hydrologic cycle is important because it is how water reaches plants, animals and us! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.

respirationcarbon dioxiderespirationWhat is the formation of foam?The formation of foam is a process when the small bubbles of the gas get trapped inside a solid or a liquid a form is made and gets made by the tapping of millions of small bubbles and can be seen in marshmallows. The process of foam formation is thus through dispersed medium and in general gas is present.
The foam is thus evidence that respiration, is taking place as carbon dioxide is a product of respiration.

Explanation:
Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
Answer:
The given statements are True.
Explanation:
The particle of the matter through which a wave move or travels is called medium. The mechanical waves can be distinguished into three types on the basis of the movement of the medium when the energy of the mechanical wave passes through, are: transverse, longitudinal, and surface waves
A transverse wave: perpendicular to the direction that the wave
A longitudinal wave: parallel to the direction that the wave

Lentic Systems and give examples
Answer:
Lentic is a class of aquatic ecosystems that are found on land, such as:
ponds
rivers
lakes
swamps
streams
Mostly, lentic ecosystems are described as still bodies of freshwater, and they are smaller ecosystems. Some lentic ecosystems contain animals and microorganisms, but they mostly rely on the photosynthesis of algae and underwater plants to produce energy to thrive. One of the requirements of a lentic body of water is that it is exposed to the sun to encourage photosynthesis.
Explanation:
A lentic ecosystem entails a body of standing water, ranging from ditches, seeps, ponds, seasonal pools, basin marshes and lakes. Deeper waters, such as lakes, may have layers of ecosystems, influenced by light. Ponds, due to their having more light penetration, are able to support a diverse range of water plants.
