Answer: By keeping plastic from being dumped in to the water, especially water in witch animals inhabit. also by using reusable cups instead of plastic bottles.
Explanation: Hope this helps!
Three examples of marine genetically engineered organisms are:
1. AquAdvantage salmon is genetically engineered Atlantic salmon modified in order to achieve fast growth. A growth hormone-regulating gene of Pacific salmon is introduced in the genome of Atlantic salmon.
2. Grass carp was also modified by scientist in order to enhance its protection from contagious diseases. It has been modified with a transgene coding for lactoferrin (antibacterial function). So, the, survival rate of the modified Grass carp was doubled comparing to nonmodifeied fish.
3. Zebrafish is the most commonly used for modification because it has 1-cell embryo, with clear chorion so it is easy to be micro-injected with transgenic DNA.
Explanation:
Echinoderms belong to a very diverse phylum of marine-dwelling invertebrates, which have integral roles in salt water aquatic ecosystems. They comprise brittle stars, starfish, sea-urchins, sand dollars, and sea cucumbers. They have distinct characteristics, they:
- are only marine animals.
- show bilateral symmetry as larvae, and radial symmetry as adults
- show three layers (germ)
- show complex-level organisation, i.e. organs are seen
- have a fluid-filled body cavity

Answer:
Cyanobacteria or blue-green algae are found in the following places:
- Freshwater (rivers, lake, ponds, streams and hot springs)
- Marine (seas, oceans)
- Soil
Explanation:
Cyanobacteria:
Cyanobacteria or blue-green algae are photosynthetic prokaryotes that inhabit a wide range of habitats. They are found as free-floating plankton in marine and freshwater environments or attached to rock surfaces as mats and periphyton (biofilm).
Cyanobacteria can either be unicellular or filamentous. They are resilient microorganisms that can inhabit the most harsh environments on Earth. Apart from the aforementioned habitats, cyanobacteria are also found in hot springs, desert soil and saline lakes.
Answer:
chlorophyll
Explanation:
The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. Some plants need more sunlight than others, but all need at least a little. Instead of taking in oxygen and breathing out carbon dioxide like animals do, plants take in carbon dioxide from the atmosphere.
