Marine dead zones can form when nutrient run-off causes certain types of algae to grow very quickly and then die off. As dead al

gae decompose, oxygen is removed from the water. With less oxygen available, fish and other marine animals can die. What would be one practical way to reduce marine dead zones?
A: Add bacteria that are able to eat the fast-growing algae.

B: Harvest marine fish in dead zone areas to reduce oxygen use.

C: Pump oxygen into the water using equipment on fishing vessels.

D: Prevent fertilizer and other wastes from entering rivers and streams.

Carnivores' biological traits aid in their ability to hunt. Wolves and other carnivorous mammals have powerful jaws and large, sharp teeth that enable them to seize and tear apart their food. On the other hand, plant-eating animals typically have large molars that aid in the grinding of leaves and grasses.

Carnivores are the largest animals in the world. The blue whale can grow to be 30 meters (100 feet) long and up to 180 tonnes in weight (200 tons). It eats by gulping down large amounts of water and filtering out microscopic krill organisms, which resemble shrimp. About 40 million of the tiny animals, or 3.6 metric tonnes (4 tonnes), can be consumed daily by blue whales.

The polar bear, which mostly consumes seals, is the largest terrestrial carnivore. Sharp claws are a hunting tool for cats like lions, cougars, and other species. Birds with talons, often known as claws, use them to hunt, including hawks and owls. The curved beaks of many carnivorous birds, known as raptors, are used to break apart their prey.

A metric that measures the decline in population sizes, shrinkage of species, and geographic range is ________.
Minchanka [31]

Answer: Living Planet Index

Explanation:

The Living Planet Index is a survey measure of global biodiversity status based on the population abundance of vertebrate species in terrestrial, freshwater and marine habitats. We have to consider that a population is defined as a species within a geographical area. <u>It is used as a source of information to identify threats at the population level for each species on Planet Earth</u>.  

With this analysis, an overall decline of about 60 percent in population size has been seen between 1970 and 2014. The decline in species populations is particularly greatest in the tropics, with South America and Central America suffering the most dramatic decline. The numbers of freshwater species have also declined dramatically. However, measuring biodiversity (all the varieties of life that can be found on Earth and the relationships between them) is complex, so the index should consider indicators to measure changes in species distribution, extinction risk and changes in community composition.  

<u>The goal of the Living Planet Index is to achieve and promote global conservation of animals and their habitats.</u>

Why are non native species with invasive traits a threat to ecosystem
liubo4ka [24]

<u>Answer:</u>

Any ecosystem is designed with a particular necessity that drives it's entire organisms that is residing in the particular ecosystem. Invasion by other species would deprive the initial nutrients that are contained in an ecosystem for it's native species.

This in turn would gradually make the native species extinct. The ecosystem contains all the nutrients that are enough for its residents and it is perfectly balanced by the nature, but invasion of a non-native species would break the natural balance and create deficit.
