Question

Raghav wants to undertake a survey to support the hypothesis “Non-native invasive plants
make it difficult for native plants to grow.” The steps that are required are listed below, but in a
jumbled order.
i. As per your observation, make a note of the numbers of species that are suspected to be
invasive in this area.
ii. If possible, compare with spaces that do not have any invasive species.
iii. Identify or earmark an area for study.
iv. Note the time for the growth (in size as well as numbers) of invasive species which
grow very rapidly over the other species.
v. Read about invasive species from books, newspapers and online resources.
vi. Take careful tour of the area to locate invasive plants by using images from books and
newspapers.
vii. Observe the death/ diminishing of some native species.
viii. Identify native and invasive plants of the locality/ surrounding area.

Answer 1

Answer:

c) V,VIII,III,VI,I,VII,II

Explanation:

Answer 2

The order of required steps is V, VIII, III, VI, I, IV, VII, II.

• At first, we read about invasive species from books, newspapers, and online resources.
• Then we identify native and invasive plants of the locality/ surrounding area.
• Then we identify or earmark an area for study.
• We take a careful tour of the area to locate invasive plants by using images from books and newspapers.
• As per our observation, we make a note of the number of species that are suspected to be invasive in this area.
• We note the time for the growth (in size as well as numbers) of invasive species which
• grow very rapidly over the other species.
• Next, we observe the death/ diminishing of some native species.
• At last,  if possible, we compare with spaces that do not have any invasive species.
