Three human activities lead to a loss of terrestrial habitat are
- farming
- deforestation
- construction
<h3>
What is deforestation?</h3>
- Deforestation, also known as forest clearance, is the removal of a forest or tree stand from land before it is put to another use other than that of a forest.
- Deforestation can occur when forestland is converted to agricultural, ranching, or urban uses. Tropical rainforests experience the highest concentration of deforestation. At the moment, woods encompass about 31% of the Earth's land area.
- This represents a loss of one-third of the forest cover that existed prior to the development of agriculture, with the last century accounting for half of that loss. An area the size of Bangladesh's forest is lost each year between 15 and 18 million hectares. 2,400 trees are typically felled every minute.

Answer:
Nucleus
Explanation:
The nucleus is the genetic center of the eukaryotic cell because it contains the genetic material (DNA, RNA) used for the storage of genetic information
All members of Kingdom Protista are eukaryotes, since their cell(s) possess a nucleus and membrane-bound organelles. Protista species can be distinguished from Kingdom Fungi by the lack of chitin in their cell walls, and from Kingdom Plantae by their sexual reproductive structures.
<h3>What are protists?</h3>
- Protists are simple eukaryotic organisms that are neither plants nor animals or fungi.
- Protists are unicellular in nature but can also be found as a colony of cells.
- Most protists live in water, damp terrestrial environments or even as parasites.
- The primary feature of all protists is that they are eukaryotic organisms.
- Protists exhibit locomotion through cilia and flagella. A few organisms belonging to the kingdom Protista have pseudopodia that help them to move.
- Protista reproduces by asexual means. The sexual method of reproduction is extremely rare and occurs only during times of stress.
